   Hi Russ,



   Although the sky is cloudy, the students are still planning to come out
tonight.  They will leave Purdue at 8:35pm.



   Looks like we will only have the slide show and basic tour of PGO.



   Thanks,

   John R.

     Hi Russ,



     Actually this is perfect as it avoids issues of moonlight during the
observing sessions.



     I will relay the message to Purdue and we will plan for the week of Nov.
9-12.



     Thanks again,

     John R.

     John....



     Thanks for your e-mail.



     Next week Nov. 2,3,4,5 is NOT NOT good.



     The following week is much better.  3 evening meetings popped up next week
that will be a big problem.



     CALL ME if we need to fine tune...but the Next week you mentioned is OK and
I will do my best to keep it that way....

       Hi Russ,



       Just wanted to check-in with you.

       Are we having the labs on Nov 2-5 as planned or the week of Nov 9-12?



       I believe it is next week, but I want to be sure.



       Thanks,

       John,



       I have checked with our volenteer support team and my family calendar.



       It looks like November 2,3,4,5  will work out best for Purdue University
Astronomy Lab visit to Prairie Grass Observatory.



       I will  offer Hot Chocolate this year to help fund Camp Cullom and the
observatory (since our only source of income is this sort of thing or donations)



       We will still provide free access on on-site volenteer help, of course,
but this way, we  can  provide a welcome warm drink for your students, if they
want....and would allow us to help support the mission of the Observatory. My
wife will run the refreshment station for us.



       We have beefed up our meteorite collection and I think your students will
enjoy that. (We have another very nice meteorite from Siberia, among others) 
All scopes are tuned up and working pretty well...and dome is repainted and in
good shape.



       (all proceeds from Hot Chocolate,etc. benefit the Observatory, and Camp
Cullom, which is a 501 C-3 Corporation.)



       Looking forward to another good learning experience for your Astronomy Lab
students.   John Mahony (who discovered the Astroids) should be there as well,
to answer questions, etc.)



       We may be able to have as many as 5 volenteers each night to man all the
stations, if all works out well.

I sent an e-mail to John Rubacha, our Purdue contact after he requested
confirmation on PGO outting. I indicated we will NOT be able to do the Purdue
Lab at PGO next week: Nov 2,3,4,5.

The following week is what we are shooting for.

November 9,10,11,12.

I had three night meeting pop up for next week, plus the full moon problem, etc.

Any help on these nights (November 9,10,11,12) is critical/appreciated.
Thanks...
Russ

This is just a reminder that we have a brand new Orion
6" Starblast reflector we would like to sell at a very nice price.
Our loss would be your gain.
Weighing only 23.5 pounds, it would make a very easy-to-use "go-scope."
The Dobsonian mount and 750mm focal length tube require no set up and
allow for instant views.  The red-dot finder was replaced
with a REAL 6x30 finder scope.

If you are wanting a good scope to give as a Christmas
gift, this one would be a bargain.

Current Orion catalog price, including S&H, is $336, and that
does not include the upgraded 6X30 finder which cost about $37.00.

We're willing to sell the scope for $260.
Contact by email or phone (765) 463-4447.
Out of town?   We'll call you.

Leah and Marilyn Sameh

The scope was purchased new in the spring, but Leah found
it too heavy for her to handle alone.  The scope has only
been outside for trial one time.

Camp Cullom's annual "Graze 'n' Gaze" coincides with PGO's final public
night of the year on Saturday Oct 17.  Chili and s'mores and other extras will
be served from 4:30 to 7:30 at the lodge.  Here are the prices for the
chili dinner:

Adults   $7.00
Youth  4 and up $5.00
Under    3
Free
That's
how it's printed on the tickets.  Note the age ranges "4 and up" and
"under 3" leaves out kids between 3 years and 3 years 364 days.  I
guess if your kid is that age you'll have to arm wrestle the person at
the front door to decide if he has to pay.

Star gazing is free, as soon as it gets dark.

Just a note on your terminology:


A "wider" passband would normally mean that the range of wavelengths
passed (around a particular wavelength) is wider.  For example, H-a
solar filters come in two flavors.  In a perfect world they would only
have to pass the H-a color, at 6562.8 Angstroms (that's 656.28
nanometers- 1 Angstrom is 1/10 nanometer.  This is very red.)  But the
sun is moving- rotating, mostly.  So the emitted red H-a gets
doppler-shifted depending on where on the sun's surface it's coming
from.  The east half of the sun's surface is rotating towards us, and
the west half is rotating away, so the east side is slightly bluer, and
the west is slightly redder, than 6562.8 Angstroms.  And on top of
that, the prominences themselves are moving, so the color of those is
also slightly shifted.  So there has to be some small range of
wavelengths passed by the filter (for that matter, I don't think it's
possible to produce a "perfect" filter for a single wavelength).



It's more expensive to produce extremely selective filters, so there
are two common versions of H-a solar filters, a cheaper version (about
$750-$1000), with a bandpass of about 1.5 to 2 Angstroms, called
"prominence" filters, and a more expensive "narrowband" or
"sub-Angstrom" version (about $3000), with a passband of about .5
Angstrom.  The widerband version lets enough non-Ha light from the
sun's surface that you can't see Ha detail on the surface, but you can
see prominces extending out from the edge of the sun into space, since
there they're seen against dark space (with a lot of glare from the sun
scattered by our atmosphere, but these filters are selective enough to
filter enough of that out).  But on the surface, the sun's other
"non-Ha" light is so strong that only the very selective "sub-Angstrom"
filters will let you see the H-a detail there.



In the world of light pollution and nebula filters, an H-a filter, an
H-beta filter, an O-III filter, or a UHC filter, if made by the same
manufacturer, would probably all have the same passband width.  The
difference is that the UHC has multiple passbands, one for each of the
three wavelengths (actually O-III refers to two slightly different
wavelengths), while the others pass only a single range each (or two,
for the O-III).  On the other hand, a "light pollution rejection"
filter is sometimes called a "broadband" filter, because while it
passes the same 3 (or 4, really) wavelengths as a UHC filter, it has a
wider "passband" around each color, to let more starlight through so it
works (a little) better on stars, star clusters, and galaxies.  But
then it also lets more light pollution through.



(And as a technicality, since O-III is actually two closely spaced
wavelengths, an O-III filter usually has a wider passband than an H-a
or H-beta filter, centered around the "average" of the two O-III
wavelengths, rather than trying to make a filter with two very sharp
closely spaced peaks in the transmission graph.)



So in comparing the Orion Ultrablock to an O-III filter, where the
difference is that the O-III passes only O-III, while the Ultrablock
passes both O-III and H-beta, it would be more accurate to describe it
as having _more_ passbands, and not as having a "wider" passband,
because it passes two different colors.



On the other hand (to add to the confusion), in the real world, H-beta
is close to O-III, so they probably do, in practice, make the
Ultrablock just by using a wider passband around O-III, to include
H-beta.  So technically, you're probably correct here, but it's a
little confusing.

Hi, John,

Thanks as always for thorough answers.  We have the Orion UltraBlock
filter which, as you say, is a slightly wider band pass than the
OIII.  I've just been wondering if it's worth the money (slightly
more than the UltraBlock) to also have an OIII.  The books recommend
the OIII for planetary nebula, and I've just wondered if they
would come in clearer with my 6" reflector with the OIII.              I'll wait
for some kind of sale and see by what percent I can get a reduction before
making a decision, I guess.

I wish someone had one which I could try before some good
planetaries vanish in the west.  I've been 'into' another
of the A.L. 'clubs' and I've had to find several planetaries,
which are very ho-hum for the most part.  I'm wondering if
M57 would be improved by an OIII.

Thanks again,
marilyn

The Orion Ultrablock isn't quite an O-III filter.  It also passes H-beta, which
is also in the blue-green part of the spectrum.  So it's in between an O-III,
and a more general UHC type nebula filter, which would pass O-III, H-alpha, and
H-beta.  UHC is "ultra high contrast", which is a name I think first used by
Lumicon, but now also used by other manufacturers for this type of filter.

useful for photography or CCD imaging than for visual observing.

The "Skyglow" filter (from Orion) is different from a UHC type.  The Skyglow is
a "broadband" (Meade's name for their version) "light pollution rejection" (LPR)
filter.  The idea is to try to block the more common types of light pollution,
and have wider passbands around H-a, O-III, and H-beta, to let more starlight
through, so in theory they should be at least somewhat useful for
stars/clusters/galaxies.  But I've never met anyone who's happy with their
performance.

Planetary nebulas tend to have more O-III emission relative to H-a or H-b than
diffuse nebulas, so O-III filters are particularly useful for them.  But for
nebulas in general, either a UHC, or  the Orion Ultrablock, or an O-III, are all
good.  As you move from UHC to O-III, you'll get a darker background, but the
stars will also be darker, and you may lose some H-a nebula light.

My answers are yes, I don't know, and yes.

I don't have a terrible problem with light pollution, but it's there; in fact,
there is no place in Indiana that can seriously be considered free of it.

The following is my opinion, based on some experience in using various kinds of
filters over the course of 26 years.

If there is any single filter you should buy for deep-sky VISUAL observing, an
OIII filter should be it. Your eyes are most sensitive to green light, and this
is what the OIII filters pass. It doesn't have to be a Lumicon, though -- the
Orion Ultrablock (which I have) is quite serviceable, and Meade, Televue and
Baader all sell their own versions.

UHC/Skyglow-type filters pass H-alpha light too, and there's a lot of that in
emission nebula. Unfortunately, your eyes are not particularly sensitive to
those wavelength, and the bandpass can be uncomfortably close to the emission
lines of low-pressure sodium lamps. For that reason these filters may be more
useful for photography or CCD imaging than for visual observing.

Also be advised that filters aren't going to help you with objects that emit
continuum-source radiation. This means you won't get much, if any, contrast
improvement viewing stars or things composed of stars (i.e.: star clusters,
galaxies).

Check out
http://articles.adsabs.harvard.edu/full/1994JBAA..104..231B/0000231.000.html for
an overview of filters. Hope this helps!

A question for owners of OIII filters:

Do you like having one?
Are they useful on reflectors as small as 6"?
Are they helpful for planetary nebulas, as I've read?

To PGO fans,

Early in April I bought an Orion Starblast 6" telescope.  I knew it would not be
as heavy as a regular Dobsonian 6", but I am finding it to be a little heavier
to handle than I thought.  It weighs about 23 pounds.  It's too hard for me to
handle and I need help with it.

If anyone is interested in buying it, I would like to get $260 for it.  I also
bought an Orion 6x30 finder for it.  I have only had it outside about 4 times
and it is still new.  I have everything that came with it.  This telescope gets
excellent ratings from both Sky & Telescope and Astronomy magazines.  It
requires virtually no set-up, is ready in an instant, and would make a very good
"go-scope" for someone with more bulky equipment or for someone who does not
want to deal with a lot.

Current Calalog Prices

Telescope:      $279.00
S&H:             $56.95
Cost of Finder:  $36.95
        TOTAL:  $372.90

(You can check this scope out at the Orion website at www.oriontelescopes.com. 
There is a PGO open house this Friday.  I could bring it if someone is
interested in  it.)

I also added some photographs of my stuff under "Jim Ehlers"

I can only say "go".  Highly recommended.

Hi,

Took some photographs from the last PG 2009 STAR PARTY.  Check them out under
the photos section "2009 STAR GAZE".  I hope everyone had a great time -- I did.

I'll be at the Great Lakes Star Gaze in a few weeks.  Everyone that has a chance
should go.  Darkest site I've seen yet.

Regards,

Jim Ehlers

I talked to Chad Evans TV 18 today.  Chad will be prepared to do the Weather
teaching module after Pizza  lunch.

I also talked with Karl Krueger.  Karl will do the Physics of Flight module
after Chad.   Karl will bring rockets for student assembly ...and is working out
the abiltiy to attach an Altimeter device to a rocket...and the kids will be
able to download data from launch onto computer!

Peggy picked up T-shirts and is also ordering shirts for the Science Exponents
(Adult helpers that day)  (Teachers, Guides, and Facilitators)

October 3rd is going to be great!

   T-shirts are done, I just have to pick them up.  All permission slips are out
to students and I even have some coming in.  We have snacks & hot dogs and will
go back to the food bank after the open house for disc golf to see what else we
need.  Peggy

     Great news!!

     Lonnie Puterbaugh will be bringing his Astronomy Van and considerable
Astronomy Knowledge to the Camp Cullom Academy of Science for our 5th Graders on
Saturday,  October 3rd, 2009

     He will not be giving a lecture in late afternoon...just the evening
presentation.  This will be after the cook-out for students, faculty and
parents.

     Although there will be a full moon at that time....Lonnie will be impressive
even under cloudy conditions...so this will be a great asset to the days
line-up.

     All is going well, T-Shirts are ordered, Leah Harden is in and no hitches as
yet, that I know of.

But I should have spelled it "Pollux".

It's too late if you missed it- I wish I had known earlier! - but the shuttle
undocked from the space station about 6 hours ago, and they just flew over
northern Indiana separated by only a few degrees, between about 9:15 and 9:20.

  I was sitting on the deck of my apartment, facing west, and saw what looked
like Castor and Pullox (the bright stars marking the heads of the twins in
Gemini) in the wrong part of the sky.  Then I noticed they were moving.  By pure
luck I had my binoculars with me, so I could tell they were not high planes.

They moved from southwest to northeast, and it was a very high pass- my
satellite tracking software says they passed within about 20 degrees of the
zenith.

-John
