HI Samarth,
I would like to introduce you to Amateur Astronomers Association of Delhi or
popularly known as AAAD. Its a very active group with its base at Nehru
Planetarium.Usually there is a meeting on every sunday. AAAD holds regular
skywatch sessions at planetarium along with an overnight observation near every
new moon. Also AAAD members interact with public during any public outreach
program or on any celestial event. We also use planetarium sky theatre sometime
to explain the sky to the new comers....
You can come to planetarium on any sunday around 1.00-1.30 pm and can meet the
amateurs there....
Sneh Kesari

Thank you everybody. Well, the Canon 1000D is quite affordable as compared to
other DSLRs; thanks for that tip. It seems that I forgot to mention I'm 12, so
maybe you all suggested quite large telescopes for my age. And the 6" telescope
suggested by Mr. Devgun will surely burn a hole in my father's pocket. So, I
think I'll be able to buy only a 4" or 5" telescope. Also, as I am about to
finish SPACE club module 2, can anybody suggest some other astronomy group
(other than e-groups!), so that I can remain in touch with other amateur
astronomers?
Clear skies!

Thank you for your help, Mr Talwar. Much appreciated.
But some of my questions still remain unanswered. I want to buy a good and
affordable telescope. Can you please guide me? I also want to know whether
astrophotography will be a rewarding experience. Will it be fruitful to buy a
camera worth INR30,000 and using it only on rare occasions? By chance, if I get
bored with photographing the skies every other day, can I use a DSLR as a normal
camera? Or will I have to use it only on celestial events?

Hello Samarth,
If you already have a camera, start using it for astrophotography. Check out for
how long it can expose. Generally compact cameras can be kept open for about 15
to 30 seconds. Try different ISO and aperture settings. In short go fully manual
and try each setting. In no time you will be familiar with the workings of your
camera. You will need a tripod to go with your camera. Next look for a dark
location and also keep a lookout for events in the sky like the upcoming
Geminids, Lunar eclipse etc.
If you are looking to buy a new camera, my advise is to go for a Digital SLR.
Canon 1000D is a good starter DSLR. In fact it is better than other more
expensive Canon models because it is a newer model.
Benefits of SLR in astrophotography
can expose for long duration, a wide range of exposures settings
better aperture than compact cameras
larger sensor size
remote control, can be controlled with computer for automated clicking
focusing is easier and better
SLR camera can capture in RAW format, which is better and high resolution than
Jpeg
In short you can have far greater control of each setting in a SLR camera than a
compact camera
In SLR cameras you can remove the lens and change it at will, you can even
attach it to a telescope, prime focus method which gives brighter images
With compact cameras you cannot remove the lens and can be coupled to a
telescope only in Afocal method, which gives fainter images as the magnification
is more, consequently you can only image brighter objects like Moon, Planets,
Bright stars, Sun.
More questions are welcome.

Dear Samarth
Most of the people solved you problem related to astrophotography and most
of them are SPACE Members as you are of SPACE Family. Welcome to the club.
I would like to answer your following question
I also want to buy a good telescope. Can anybody suggest a good, affordable
one? I fear that if I observe the same things everyday, I'll get bored. So
please can someone guide me?
Dear Samarth.
AS CB guided you to start with atleast 6" telescope you can go for 6" or
bigger OTA with a German Equitorial Motorised MOunt where you can go for
both the sutffs Visual Photography and also AstroPhotography. Also other
affordable options are available if you opt for non motorised mounts but
your astrophotography will be limited to planets and moon with the help of
AFOCAL Equipment. All these things are available at "Gnomon AStrotech" a
branch of SPACE . Please visit www.gnomonastrotech.in or you can go directly
there and get help for yourself.
thanks

Hi Samarth,
How big a telescope you want is purely determined by what you want to view.
If all you want to view is planets and some bright Deep-Sky Objects (DSOs)
even a small 5 inch telescope will do you good (and not burn a hole in your
pocket).
But what do you want to view? That is a tough question knowing the fact that
you probably haven't viewed both planets and DSOs through a telescope
before. Also, you probably don't know just yet how deep you want to go into
amateur astronomy/astrophotography. So it is my humble suggestion, that you
start with a small telescope, and since you won't be doing any worthwhile
DSO astrophotography with it, a cheap dobsonian mount. Also, surprising as
it may sound, all you need to start on astrophotography is a cheap of-the
shelf webcam (I use a logitech quickcam worth Rs. 400 and that does the job
for me). Webcams are extremely good when it comes to planetary
astrophotography. I can show it to you if you're interested. See the link
below to view some of my pics (all taken either from a webcam or a Sony
digicam (not a DSLR)).
http://picasaweb.google.com/anishmangal2002
I say this since I sense that may spend 30k on a big scope, another 30k on a
DSLR and end up not having the time, skill or patience to do serious
astrophotography.
On the other hand, if you're completely sure that you are indeed (or want to
be) an 'astronut', then dive right in! You may even consider making a
telescope instead of buying one (This are is aptly called Amateur Telescope
Making). There are excellent resources on the internet and you'll be
surprised how easy it is to MAKE a telescope. Besides, it would be extremely
rewarding and satisfying a experience.
Hope that I have made things are a little clearer instead of more confused
now ;)
And, owning a DSLR is probably a good decision anyday, astronut or not. I
plan to buy one soon too ;)
Regards,
Anish
Btw, this is the start of what we call as "Aperture Fever"

Hey Samarth, let me try and solve some of ur questions with the little
experience I have...
Anything you like and u do it, u will never get bored...as far as
astrophotography is concerned Its a rewarding experience for me. When I plan
something and get it in my memory card, I am relaxed and happy too, but if
things go wrong, its not a failure but a learning experience.
After seeing Ajay and lerning from him for over 4 years, I recently purchased a
DSLR from Canon (500D for 47K) and use it every now and then. I use it as a
normal camera d other day if nothing grt to click in the sky. So my camera is on
work almost daily.
If u can try new gears for ur cam or scope and varying ur style of work, there
is nothing u'll get bored of...Also if u are a good learner...u will never
regeret...
I would suggest you to start slow and first join us for some observation and see
how things work, the great images are not that grt initially so having
experience is always recommended...thats how I started...
BTW Canon 1000D is a grt cam and is for 27K approx....I have seen Himanshu
taking some very nice images with that. Also there are plenty of objects in the
sky to shoot, so u may get bored of one object but not of shooting for sure....
I dont own a scope so cant suggest u on that...
Hope I am of some help to you...

Hello Samarth,
If you already have a camera, start using it for astrophotography. Check out for
how long it can expose. Generally compact cameras can be kept open for about 15
to 30 seconds. Try different ISO and aperture settings. In short go fully manual
and try each setting. In no time you will be familiar with the workings of your
camera. You will need a tripod to go with your camera. Next look for a dark
location and also keep a lookout for events in the sky like the upcoming
Geminids, Lunar eclipse etc.
If you are looking to buy a new camera, my advise is to go for a Digital SLR.
Canon 1000D is a good starter DSLR. In fact it is better than other more
expensive Canon models because it is a newer model.
Benefits of SLR in astrophotography
can expose for long duration, a wide range of exposures settings
better aperture than compact cameras
larger sensor size
remote control, can be controlled with computer for automated clicking
focusing is easier and better
SLR camera can capture in RAW format, which is better and high resolution than
Jpeg
In short you can have far greater control of each setting in a SLR camera than a
compact camera
In SLR cameras you can remove the lens and change it at will, you can even
attach it to a telescope, prime focus method which gives brighter images
With compact cameras you cannot remove the lens and can be coupled to a
telescope only in Afocal method, which gives fainter images as the magnification
is more, consequently you can only image brighter objects like Moon, Planets,
Bright stars, Sun.
More questions are welcome.

really needed? I mean, to take pictures of the moon and the planets, do I need
an slr? Also, I need one which is affordable, useful and efficient. Can anybody
suggest one good enough for me? It'll be a great help.
I also want to buy a good telescope. Can anybody suggest a good, affordable one?
I fear that if I observe the same things everyday, I'll get bored. So please can
someone guide me?

Hello Samarth,
Astrophotography has been quite rewarding, satisfying activity for me. I have
also seen many a people around me get fascinated by astrophotography, from then
on they are constantly thinking about getting different types of sky pictures
and getting better.
You can use a DSLR for all purposes, you can use it as a normal camera too.
Normally you are not going to modify anything inside the DSLR to make it
unsuitable for normal daylight photography. (only some astronuts like me think
of modifying a DSLR).
I can't think of a situation where I can get bored with photographing the skies,
but that's just me. Also I don't go photographing the skies every other day!
only bigger astronuts than me do that king of thing. I AM planning to upgrade
myself to that stage, and want to install a telescope on my terrace, so I can
photograph planets as an everyday 30-40 minute activity from the comfort of my
study.
In short, I'd like to say that you will not regret buying a DSLR camera at all.
Maybe Himanshu, Sneh, Atish, Raghu and other DSLR owners can mail their
experiences.
Ajay Talwar

Thank you for your help, Mr Talwar. Much appreciated.
But some of my questions still remain unanswered. I want to buy a good and
affordable telescope. Can you please guide me? I also want to know whether
astrophotography will be a rewarding experience. Will it be fruitful to buy a
camera worth INR30,000 and using it only on rare occasions? By chance, if I get
bored with photographing the skies every other day, can I use a DSLR as a normal
camera? Or will I have to use it only on celestial events?

Hello Samarth,
If you already have a camera, start using it for astrophotography. Check out for
how long it can expose. Generally compact cameras can be kept open for about 15
to 30 seconds. Try different ISO and aperture settings. In short go fully manual
and try each setting. In no time you will be familiar with the workings of your
camera. You will need a tripod to go with your camera. Next look for a dark
location and also keep a lookout for events in the sky like the upcoming
Geminids, Lunar eclipse etc.
If you are looking to buy a new camera, my advise is to go for a Digital SLR.
Canon 1000D is a good starter DSLR. In fact it is better than other more
expensive Canon models because it is a newer model.
Benefits of SLR in astrophotography
can expose for long duration, a wide range of exposures settings
better aperture than compact cameras
larger sensor size
remote control, can be controlled with computer for automated clicking
focusing is easier and better
SLR camera can capture in RAW format, which is better and high resolution than
Jpeg
In short you can have far greater control of each setting in a SLR camera than a
compact camera
In SLR cameras you can remove the lens and change it at will, you can even
attach it to a telescope, prime focus method which gives brighter images
With compact cameras you cannot remove the lens and can be coupled to a
telescope only in Afocal method, which gives fainter images as the magnification
is more, consequently you can only image brighter objects like Moon, Planets,
Bright stars, Sun.
More questions are welcome.

Dear Samarth,
you want to have a telescope for planetary viewing or DSO (Deep Sky
Objects), that will decide which one to go for. For a start you can go for a
150mm reflector mounted on an equatorial mount which will be just perfect
for planetary as well as DSO viewing and you can also attached your camera
to it to take photographs. If you don't want to go for astrophotography with
a telescope ten you can opt for a dobsonian which is user friendly in
observations as its very easy to handle. You can search the site of
www.gnomonastrotech.in for various option available.
You can get a good DSLR in range of 30k and remember that a DSLR is not just
a cam for astrophptography, its a camera made to take normal photographs but
we astronomers and astrophotographers can make it take the astrophotos. So
you don't have to worry as whether that camera will be useful for normal
photography or not. It will be. Have a look at the various terrestrial and
astrophotos I as SPACE team member took with diffrent DSLRs at
http://www.flickr.com/photos/devgun/ and the simple ones with no hifi things
attached to it at
http://picasaweb.google.co.in/chander.devgun/AstrophotographyWithTripod

Thank you for your help, Mr Talwar. Much appreciated.
But some of my questions still remain unanswered. I want to buy a good and
affordable telescope. Can you please guide me? I also want to know whether
astrophotography will be a rewarding experience. Will it be fruitful to buy a
camera worth INR30,000 and using it only on rare occasions? By chance, if I get
bored with photographing the skies every other day, can I use a DSLR as a normal
camera? Or will I have to use it only on celestial events?

Hello Samarth,
If you already have a camera, start using it for astrophotography. Check out for
how long it can expose. Generally compact cameras can be kept open for about 15
to 30 seconds. Try different ISO and aperture settings. In short go fully manual
and try each setting. In no time you will be familiar with the workings of your
camera. You will need a tripod to go with your camera. Next look for a dark
location and also keep a lookout for events in the sky like the upcoming
Geminids, Lunar eclipse etc.
If you are looking to buy a new camera, my advise is to go for a Digital SLR.
Canon 1000D is a good starter DSLR. In fact it is better than other more
expensive Canon models because it is a newer model.
Benefits of SLR in astrophotography
can expose for long duration, a wide range of exposures settings
better aperture than compact cameras
larger sensor size
remote control, can be controlled with computer for automated clicking
focusing is easier and better
SLR camera can capture in RAW format, which is better and high resolution than
Jpeg
In short you can have far greater control of each setting in a SLR camera than a
compact camera
In SLR cameras you can remove the lens and change it at will, you can even
attach it to a telescope, prime focus method which gives brighter images
With compact cameras you cannot remove the lens and can be coupled to a
telescope only in Afocal method, which gives fainter images as the magnification
is more, consequently you can only image brighter objects like Moon, Planets,
Bright stars, Sun.
More questions are welcome.
Ajay Talwar

Hi Anish,
I know only of Mr Suresh Mohan of Chennai who has a modified Canon 350D, it was
modified by Hap Griffin in USA.
There
are several tutorials as well as videos available on the internet for
making the modification. I have contemplated several times to modify my
camera but have resisted it till now. There is simply too much stuff in
the sky to photograph reasonably well without the modification. Also I
did manage to photograph the Rosette nebula nicely with my unmodified
Canon 450D, a nebula which is considered reserved for modified cameras
only.
Canon did make an astrophotography friendly camera called
the 20Da, which did not have this filter in front. They made only
limited quantities, I heard about 1000 pieces. The model is now
discontinued. (As an aside I do wonder if 20Da had live view enabled, I
would consider live view to be a very important consideration in
astrophotography, by experience, I've wasted many a hours focusing my
Nikon D70, which is without live view)
There
is a discussion going on in Digital_Astro about the same thing,
apparently Canon produced the 20Da, because some one very high up in
Canon corporate is an amateur astronomer! but otherwise there are not
many takers for Canon to consider this modification service.
Anish, if you do want to modify your camera, I can help you with the resources
that I have. Where are you located?

Hi,
As you might know, DSLR's (or for that matter even normal digicams or webcams)
have an IR-cut filter in front of the imaging sensor. This filter effectively
allows only 1/4th of the light of wavelengths corresponding to the O-III and H
lines, i.e. the nebulous glow of celestial objects. So for example, when taking
a long exposure shot of the milky way, the shutter will need to be open for 4x
the amount of time with a normal DSLR when compared to one with its IR cut
filter removed.
Clearly, having the IR-cut filter removed gives astrophotographers a definite
edge. So my question to all AAAD members is :
1. Has anyone tried to remove the filter from the front of the DSLR (and
succeeded)
2. Has anyone contacted canon/nikon to replace the IR filter with a clear glass
plate of equivalent thickness in front of the imaging sensor. Perhaps, if we as
a group decide to buy a quantity of canon DSLR's, we might succeed in persuading
canon to make this modification (which must be relatively simple for them)
FYI, This type of modification of canon cameras is done professionally by third
party people at a price abroad.
Regards,
Anish

Please see the following:
http://nehruplanetarium.org/taarewiki/pmwiki.php?n=Site.GalileoAFilmByLilianaCav\
ani
Tomorrow evening is the finale of the Indo Italian Astronomy Fortnight.
It is going to be an interesting mix of Galileo, the Moon and the Pleiades
tomorrow evening - starting at 6 PM in the auditorium of Nehru Memorial Museum
and Library.
There is the screening of a recently restored version of a 1969 film on Galileo
by Liliana Cavani - the film will be with English subtitles.
As it happens, there is the Lunar occultation of Atlas (one of the Pleiades)
happening at the same time!
Ajay and Vikrant are working towards a possible live feed from a small telescope
- to be placed inside the auditorium - for simultaneous viewing of the
occultation along with the film.
It will be an interesting mix, as observations of the Moon and the Pleiades -
both have IYA significance and all in all such an evening - with Galileo, the
Moon and the Pleiades seems a very IYA thing to do :-)
Rathnasree, Nehru Planetarium, New Delhi
The celebrations of the International Year of Astronomy are going to be followed
immediately by countrywide activities related to the centenary celebrations of
Nobel Laureate Subrahmanyan Chandrasekhar, who was born on the 19th of October
1910.
For interested Delhiites in this week, a common meeting point of these two
celebrations will be at the Nehru Planetarium, Nehru Memorial Museum and
Library.
As a part of the ongoing Indo Italian Astronomy Fortnight celebrations, there
will be discussions and a screening of two films on Subrahmanyan Chandrasekhar
at the Nehru Planetarium, Nehru Memorial Museum and Library, in collaboration
with the Italian Embassy, Italian Cultural Center, Delhi University and the
Akshara Theatre.
The films are : "Two and Two" by Gopal Sarman, which features live interviews of
Chandrasekhar, and "Chandra – the Journey of a Star" an Italian film in English,
written by Guiseppe Mussarab and directed by Enrico Agapito
The screening of the films will begin at 11:30 AM, on the 29th of November, and
will be followed by discussions and question answer sessions on the works of
Chandrasekhar, co-ordinated by Prof. Patrick Das Gupta and Professor Amitabh
Mukherjee, Department of Physics and Astrophysics, Delhi University.
The other highlight of the ongoing Indo Italian Fortnight, ahead, is the
screening of the film on Galileo made by Liliana Cavani, at 6 PM on the 1st of
December 2009, at the Auditorium of Nehru Memorial Museum and Library.
The Indo-Italian Fortnight being celebrated at the Nehru Planetarium, is also a
part of the 120th birth centenary celebrations of Jawaharlal Nehru, the Nehru
Imprint at the Nehru Memorial Museum and Library. An exhilarating Dhanak Din Bal
mela will be enticing children to the Teen Murti Campus of the Nehru Memorial
Museum and Library, on the 28th and 29th of November, as a part of the Nehru
Imprint celebrations.
Rathnasree, Nehru Planetarium, New Delhi
Hi group,
Its about 45 days left for the annular solar eclipse and AAAD has not yet
planned for it. I would like to ask all the AAAD members interested in observing
this eclipse to come to planetarium tomorow at 1:30 pm and share their plan for
the eclipse.

Dear Astronomads,
We had a fantastic Leonids observation from Tiger Den hotel, Sariska, Rajasthan
on the night of 17th-18th november. The observation organised by space consisted
of SPACEians, Astronomicans, Astronomds (a new unofficial gang of amitabh) and
some old AAAD friends, in total there we were 20 people on the site including 4
foregners from US. In addition to this we were also joined by Arvind and Ravi
from Vigyan Prasar and Sandeep Nigam from Star News with his crew who covered
the event.
After a careful delibration over the weather situation and considering several
alternate sites such as dumdama, jim corbet and even Hatu peak in himachal (the
most tempting option), we zeroed in on Sariska (thanks to our weatherman, CB).
Surely the decision was well taken and we were treated to cloud free skies,
except that the it was a little hazy, but we still had a limiting magnitude > 5
and we could see the milky way.
The show began with an extremely bright leonid fireball at around 12:30 AM just
few minutes before the radiant rose up above our horizon. I did not see this
fireball, but i am being told that it was about -5 or -6 mag in brightness and
left a smoke trail which could be seen for well well over 5 minutes.
While CB, Atish and Rohini attempted photographing the event (I think CB
captured few of them) Amitabh, Shotmita and I set out for visual observations
for the IMO report. I must thank Bhavneet for the great support during the
timekeeping and logging in my over 3 hour long patrol and also for helping me
compile the elaborate report along with Rohini for IMO right after from the dawn
sacrificing her sleep.
Here is a report of my observing session early morning of 18th November:
Limiting Magnitude : varied between 5.01 and 5.20
Centre of field : Castor and Pollox
Obstruction of field : None
Cloud cover : None
Total Observation Time : 3 Hours 5 Minutes
Total number of Leonids observed : 78
Total Sporadics observed : 24
Brightest Leonids Observed : 2 of -2.5 Mag.
Average brightness of Leonids observed : Between 0 and 1
Number of Bolides seen : 1
Interval Breakup :
1:45 AM to 2:45 AM IST : 15 Leonids, 9 Sporadic
2:45 AM to 3:50 AM IST : 42 Leonids, 7 Sporadic.
4:05 AM to 5:05 AM IST : 21 Leonids, 8 Sporadic
A more detailed report of the data I submitted to IMO can be accessed at:
<http://umdb.urania.be/v2/obsview/view.php?id=5754>. The data suggests that the
activity certainly was high between 2:45 and 3:45 AM, particularly a 10 minute
interval between 2:45 and 2:55 AM showed a spike in meteor rates as I saw 12
meteors during this 10 minute time, that means a leonid meteor streaked the sky
every 50 seconds or so on average.
It seems that the prediction of "as many as 200-300 meteors per hour" during
21:00 and 22:00 UT (2:30 and 3:30 IST) did not turn out to be exactly so (though
seems to be a definite spike during / around this time), the observations
submitted at IMO so far are suggesting peak ZHRs of about 133. (have a look at:
http://www.imo.net/live/leonids2009/#peak)

Tomorrow (Saturday) at 5 PM, there is a public lecture at the Planetarium, under
the Godhooli Public lecture series - titled "Journey through the Galaxy".
This is a part of the Indo Italian Astronomy Fortnight.
If AAAD members wish, tomorrow could be held as the monthly AAAD skywatch
following the public lecture.
I hope all interested amateur astronomers and students will come for the public

night
about the program to be finalised.
THe following are some quick details:
(Inauguration on the 16th November, at 6 PM at the Nehru Planetarium, by the
Italian Ambassador H.E. Roberto Toscano)
( The inaugural program (as all the other prgrams too) promises to be an
exhilirating multidisciplinary celebration of Astronomy!)
To celebrate the International Year of Astronomy and the Italian "Year of
Galileo", an Indo Italian Astronomy Fortnight titled "From Galileo to Modern
Frontiers" is being organised at Delhi from the 16th of November to the 1st of
December 2009. The fortnight is being organised through the collaboration
between the Italian Embassy, the Italian Cultural Center, Nehru Memorial Museum
and Library, Nehru Planetarium, University of Delhi, Vigyan Prasar (Department
of Science and Technology), Fondazione Centro Sperimentale di
Cinematografia-Cineteca Nazionale, La Fenice Theatre (Venice), The Anad
Foundation, the Science Popularisation Association of Communicators and
Educators (S.P.A.C.E., an NGO), the Amateur Astronomers Association, Delhi, and
Prof. Toni Hildebrandt.
A number of exhilirating and creative activities are a part of the Indo Italian
Astronomy Fortnight. The fortnight will be inaugurated with an interdisciplinary
celebration of Astronomy : An evening with Music, Art and Astronomy, to be
inaugurated by the Italian Ambassador, H.E. Mr. Roberto Toscano, in the presence
of Prof. Mridula Mukherjee, Director, Nehru Memorial Museum and Library, on the
16th of November at 6 PM at the sky theatre of the Nehru Planetarium.
This program under the stars of the planetarum sky theatre, has many interesting
creative elements : listening to sounds from celestial objects like pulsars,
Jupiter and the Sun, and viewing of celestial images reminiscent of nature
imitating van Gogh's art.
There will be the inauguration of a photo exhibition showing many examples from
classical and modern Italian art which have influences from Astronomy.
And finally, the inaugural session will have the very interesting musical
evening under the planetarium stars, presenting a Concert titled "The Time of a
Star" by Sara Michieletto and Bhai Baldeep Singh, with an interesting jugalbandi
of celestial sounds with Italian and Indian music.
This multidisciplinary celebration of Astronomy will be followed by a scientific
Indo Italian workshop at the Delhi University on the Physics and Astrophysics in
the vicinity of compact objects, organised by Prof. Patrick Das Gupta,
Department of Physics and Astrophysics. Prof. Tomaso Belloni from the National
Institute of Astrophysics, Astronomical Observatory of Brera, Italy, will speak
about the Galactic Compact Objects as Laboratories for the Physics of the
Extreme, during this workshop. The workshop will be held on the 18th of November
from 2 PM to 5:30 PM at the department of Physics and Astrophysics.
The fortnight also has a very interesting country wide video conferencing
workshop on assembling and using Galileoscopes. Utilising the Vigyan Prasar
Edusat network, the fortnight includes sessions dealing with assembling simple
telescopes and discussions on their usage to enable children to view the
inspiring views that had been seen for the first time by Galileo - the craters
on the Moon, moons of Jupiter, the phases of Venus and the rings of Saturn.
From the International Galileoscope project, through the Tech Museum of
Innovation, San Jose, USA, 20 international quality Galileoscopes have been
received by the planetarium, 10 of which have been distributed to groups
affiliated to the edusat centres around the country. The video conference is an
exhilirating opportunity of sharing the nitty gritties involved in assembing and
using these telescopes.
An exciting event to look forward to, is the screening of Bertold Brecht's play
on Galileo, at the Akshara Theatre, on the 27th of November, at 7 PM. The play
will be performed by the artistic ensemble of the Akshara Theare comprising of
celebreties like Jalabala Vaidya, Gopal Sharman, Sunit Tandon, Rajiv Chandran
and Geeta Chandran.
There will be screening of films Subrahmanyam Chandrasekhar, a film directed by
Gopal Sharman, and an Italina film in English, directed by Enrico Agapito, and
discussions for students on the works of Chandrasekhar at the Nehru Planetarium,
at 11:30 AM on the 29th November. The discussions will be co-ordinated by Prof.
Patrick Das Gupta and Prof. Amitabh Mukherjee, of Delhi University.
The conclusion of the fortnight will be a screening of an Italian film (with
English subtitles) on Galileo, made by Liliana Cavani, at the auditorium of
Nehru Memorial Museum and Library, at 6 PM on the 1st of December.

Hi
As many of you might remember the world will remember Dr. Carl Sagan on his 75th
birthday on November 9th. He was an American astronomer, astrochemist, author,
and highly successful popularizer of astronomy, astrophysics and other natural
sciences. He pioneered exobiology and promoted the Search for Extra-Terrestrial
Intelligence (SETI).
He is world-famous for writing popular science books and for co-writing and
presenting the award-winning 1980 television series Cosmos: A Personal Voyage,
which has been seen by more than 500 million people in over 60 countries. A book
to accompany the program was also published. He also wrote the novel Contact,
the basis for the 1997 film of the same name. One of the last books he wrote was
Pale Blue Dot. During his lifetime, Sagan published more than 600 scientific
papers and popular articles and was author, co-author, or editor of more than 20
books. In his works, he frequently advocated skeptical inquiry, secular
humanism, and the scientific method.
Remembering him The Amateur Astronomers Association Delhi will celebrate Sagan
Day on Sunday, 8th November 2009 , where at 12:30 there will be a special
screening of the movie 'Contact' starring Jodie Foster.
Next there will be a special lecture on Leonid Meteor Shower by astronomer Ajay
Talwar. The skywatchers at Caltech predict a great Leonid storm this year. The
Leonids are supposed to show a rate of 500 to 1000 per hour. That my friends is
nothing short of a shower-storm, and if the predictions are correct this
opportunity is not to be missed!
I invite you all to please be there to remember Dr. Sagan and have Leonid talk
with us at the AAAD room in the Nehru Planetarium, Teen Murti Bhawan , New
Delhi-11 at 12:30 afternoon.
Be there!!

Hi,
As most of you know SPACE organises overnight observations and evening
observations for the school students from Delhi, NCR and Hyderabad. Every year,
thousands of students get an opportunity to see the night sky for the very first
time because of this effort. These overnight and evening observations are part
of the Space Astronomy Club that run in various schools of Delhi/NCR and other
cities.
We are looking for amateur astronomers (or anyone who is interested) who would
join us part time for these efforts and help us conduct evening and night
observations in Delhi/NCR. The volunteers will be trained in conducting these
sessions over a two day training period. Most night observations are organised
over the weekends when the Moon phase is favourable. Evening observations may be
organised on any evening of the week (again after looking at the moon phase).
Prospective volunteers need to specify if there are particular days and
particular times that suit them for such observations.
The venue for an evening observation is the respective school while we will be
taking students to a dark observation site (ahead of Faridabad) for the night
observation.
Volunteers will receive Rs 500/- for an evening observation and Rs 750/- for a
night observation as an honorarium. A cab pick up and drop facility will be
provided. Food at the venue (for night observations only) will also be provided.
All equipment needed for an observation will be provided and a junior educator
from SPACE will accompany you at all times.
Interested volunteers are requested to send me a mail directly at
nikhil@... . (Please avoid replying to the group).
Also mention what times and days suit you best. Feel free to contact me if you
have any questions.
The observation season has started. Looking forward to quick response.
Thanks and Regards

Nice framing!!!! But the mars is lost in the glow of Moon. You can also go for
noise removal to make this pic more nice!!!!
Moon over Sagittarius also looks quite good. Thanks for sharing.

Dear members
We are extremely sorry to inform you that we will have to change our Galilean
nights observation site from cannaught place because there is an on going
renovation happening there these days and the place we had chosen for
observation has been dug up.
So therefore we will have to change our location of observation to India gate
lawns right next to the India Gate monument (facing Rashtrapati Bhawan/
President's house)itself we will start the observation by 7:30 pm IST
we are extremely sorry for the inconvenience caused

This is awsome!! =D
Quick Question - Would light painting with a flashlight help in this sort of
situation?
And if you've tried it, how do you manage to get even illumination?

Subject: [AAAD " tHe bOhEmIaNs"] Way to Via Lactea
Hello Fellow Astronuts,
It has been a month since Me & Pankaj Sharma went to latitude 31°.243 &
longitude 77°.501. So many photons gathered amidst the dark skies during the
hectic 4 nights at Hatu. Most of the photons are processed, but some still to be
changed into eye catching photographs.
Normally in hill stations you get a lot of trees and the sky gets covered with
the trees and the hill side. Its lucky that Hatu peak has all round visibility
till the horizon, and I think even below horizon! astronomical horizon that is.
The four evenings that we spent at Hatu waiting for the Sun to go down were
memorable. As twilight began, the clouds would just dissipate, vanish into thin
air. Even before the civil twilight began, Akash Ganga, Milky Way or Via Lactea
would make its appearance already. Can't seem to forget the orange of the sunset
in the west would be merging with the Milky Way clouds of Sagittarius in the
south. Beautiful.
Here is one simple photo taken with camera & tripod. Exposure 2 minutes, at 9pm.
The photo is titled 'Way to Via Lactea'. Way is of course the road the Hatu
peak, and Via Lactea is the Milky Path in the sky. Hope you like the photo.

Wishing you all a very happy Diwali.
