Greetings all.

My name is Patrick from Louisville, Kentucky am the proud owner of an 80mm f7.5
TMB
carbon fiber tube mounted on a Losmandy GM-8.  This is a most excellent
telescope that
continues to amaze my observing friends.

I posted a few pictures that I took a while back with a low cost Meade LPI.  I
enjoy reading
everyone's posts as well; very informative and fun.

Patrick

I am new to using a refractor.  I have an 80mm f7.5 TMB super-apo.  I am looking
for a focal
reducer, but am unsure what to purchase.  The scope will be used for some
astrophotography, both planetary and deep sky.  Any recommendations would be
most
appreciated.

Clear skies!

Hi all,

I was wondering if you guys could shed some light on this. I was doing
basic star test on my TMB 115/LW and I noticed that when I go slightly
out of focuse (both directions) the rings appeared to be elliptical.
I'm guessing that's the sign of astigmatism? What could be causing this?

Regards,

Zing

hi guys,

it is slightly off topic, but still - touches our interests in
astrophotography, I hope.
so, on behalf of the organizers I would like to draw your attention
to the first central european imaging conference for deepsky
photography:

Calling all astro images!

We would like to invite you to the "Central European Deepsky Imaging
Conference"
(CEDIC'09), which will take place from Friday, April 3, to Sunday,
April 5,
2009, in
Linz, Austria.

CEDIC'09 is the first international astro imaging conference in
Europe. The
agenda
of the meeting, and many more details, are available at the CEDIC web
site
at

http://www.cedic.at

Registration for the conference is also possible on
this web
site. Please note that the number of participants is limited, so
please
register
early.

Among the many talks schedules for CEID are "The ESA/ESO/NASA
Photoshop
FITS Liberator - in depth!" von Lars Lindberg Christensen (ESO/ESA)
and
"Astrophotography at Paranal: from a DSLR to VLT" by Yuri Beletsky
(ESO), to

name only two of the highlights. Many more interesting talks by
leading
astro
imagers, presentations of the newest astro imaging hardware, a
conference
dinner
in a relaxed atmosphere, and a opening event featuring top astro
images in a

breathtaking gigapixel projection will make CEDIC'09 an event not to
miss!

Please note that the city of Linz is also the European Capital of
Culture in
2009.
So much more waits here for you to be discovered, besides CEDIC.

Conference language is English.

cheers,
dietmar

Hi Paul,
     My Dad has a TMB 100/800 Classic I am quite impressed  with though he
doesn't use it for imaging. I don't have any  experience with an FLT 98 but even
then I am inclined to advise on keeping the  TMB. As you said, it has been
often stated to be one of the best  4" apos ever made if not THE best. Buuuut if
you  don't use it much for visual you might be better served with a faster
scope. But  then again you could use a focal reducer on the TMB. I personally
don't  care much for really short F refractors but the majority of use mine have
seen has been visual. A lot of EPs start showing signs of lateral  color with
the shorter focus apo refractors. And the shorter you go  the worse it gets.
Put a 41 Panoptic in an F6 and look at the moon off axis  and you'll see what
I mean. Looks like someone took a tricolor image and didn't  merge it
correctly. Even my F7s do this with that EP. And as you have  found, the longer
F
creates a longer radius of field curvature eliminating the  need for a
flattener.
Well, almost. You do have a little  corner stretch there in your M42/Running
Man shot but it's not as much as I  expected. Truly hardly noticeable. My F7 6"
and 30D produce more corner  stretch than that without the flattener and I
would have to think that it has a  longer radius of curvature. Nice shot BTW.
Did you crop it?
     A modded DSLR might reduce your exposure  times by letting more of the
red H, N and S emisions through but not  having modded my Canon I'm not sure.
Just curious, why do you want to downgrade  from the 20D to a Rebel? I'm
assuming that you use a Canon TC (timer  controller)? Are you aware that it
won't
plug into a Rebel without modifying the  plug? Of course the cost of modding the
plug plus the camera might still be less  than a 40D.
     Anyway, I hope this helps you alleviate any buyers  (traders) remorse
about the TMB.

CS,
David

Hi,

The recent spell of three clear nights allowed me to collect some
decent data on this familiar target.  I managed just over 4 hours of
photons.  I'm pleased with the result, though it was a bit of a trial
getting the calibration right on one of the sets of raw images for
some reason.  I used my modified Canon 20D, IDAS filter and TMB152.
Calibration in IRIS and post processing in Photoshop.

Comment ant critique most welcome

If you seek the same optical quality without giving up aperture or
speed, the 105/650 is super sweet too. I'd try your existing TV
reducer flattener first however, to see what you think of those
results.

hi guys,

it's been a while since my last post...
my dayjob and other issues kept me quite busy these days,...weeks almost.
nevertheless, I was lucky to find 2 decent nights and time for
imaging, too!
M81 was the target. 8.5 hours is not perfectly much total exp. time,
but enough for an image at least.

the best part was, it has gotten featured on Universe Today.
http://tinyurl.com/almjp3
within this story by Tammy Plottner you will also find a nice overview
taken by Karel Teuwen.

please find all data and my image taken with the 9" TMB And the

Hello,

You may see this result what you are looking.

I have TMB 80/600 in WO tube. I Tested with Televue TRF2008. It didn't
match. I found star elongate at the conner. In the other hand, I found
star too elongate than not use Televue reducer!!!

But I found great combination with BORG 0.85X. I measure curvature
with CCDI, it was only 9%.

Hi,

you don't need an extra spacer if you use an canon 20D, only T-ring is
required, and you will get the correct distance directly.

If you find your field not completely flat, this may be because of canon
sensor tilt (not // to focal plane) or because you are not at perfect focus
(if you focus on the center of the image, corners may be impacted, you can
try to focus half the way between the center and the borders of the image).

There are pictures of my setup with a 80/480 and TV reducer on the first
link on my website, if you want to check.

Paul,
These are beautiful images. I would keep it, maybe invest in a FR.

I nearly obtained one of these recently (the deal fell through) and
was concerned about the same issue. I ran across a paper by Craig
Stark discussing F ratio and exposure time. He contends that as long
as the image collected is above the noise floor,  the f ratio is not
important when it comes to image quality. The relationship between f
number and exposure time was driven by nonlinearity in film. Aperture
vs exposure time is the more appropriate thing to trade.

http://www.stark-labs.com/blog/files/tag-ramblings.php

I would not push someone elses research, except I have a great deal
of respect for Craig Stark's opinion

I hope it helps,

Jerry

HI David,



No the image was not cropped.. I didn't downgrade as such I brought the
1000D as it performance was similar to the

40D for Imaging (I didn't want to modify my 40D but keep it for daytime
photography.



I don't use the Canon TC with the Camera for Astro photography just a laptop
and live view.

Hello,

If you want flat field with TMB 80/600.  I have try with BORG 0.85X
reducer. This work great less than 9% curvature. It almost act like
dedicated field flattener. You need 2.5 mm. space ring too.

Hi Tom,

      These scopes were discontinued not long after the first few were sold.
Unfortunately they did not know allot about optics as they reduced the light
path down to 38mm using a coned reducer which cause reflected light to cross
the primary light path. The RC optics has a 100mm image circle, made by
Oldham Optical in the UK. I am planning to open up the rear cell using an
RCOS solid Flange adapter @ 4.O625 diameter.

http://www.rcopticalsystems.com/accessories/fia_100mm.html

and I am going to upgrade to a Van Slyke secondary focuser with RoboFocus
incorporating four vanes:

http://www.observatory.org/spiders.htm



      This should solve the bad Optics they were experiencing! <G> It is very
unfortunate they did not realize what was going on with the cone reducer
they installed, other than that is a good design. I did have to add a
counterweight in front of the fork before it would remain balanced in every
position. The main problem for me is lack of funds to make the improvements
and finish the observatory for it. I will just have to keep saving what I
can to get the scope operational.

Hi all,
Well, this was more fun than a barrel full of monkeys. It is Comet Lulin
from last Saturday night. I acquired 61 each 1 minute images with my FSQ
and STL-11000. With download time and all that it represents about 2
hours of comet movement. I then assembled the animated gif for posting.
You will notice a couple of images are noisy with some vertical lines. I
have no idea what happened, but did not want to remove them because it
would make the movie a bit jumpy. Also, it looks way better in Firefox 3
than IE, but still kinda fun. The geosynchronous satellites add to the
nifty effect.
It is a 29 MB file, be patient and let it load into your browser once
you download it. It runs in only 6 seconds when all loaded.

Let me know what you think.

Hi Tim,

      Not sure but I think they are satellites passing thru.

Hello to all,

I am a proud owner of a TMB 105/650 CNC telescope. It came with a
100mm extension tube and the other tubes (30mm and 60mm) were from
Markus of APM.

Can somebody please tell me the specific "male" threading measurements
or specs used in the extension tubes.

Thanks in advance.
