I tried Vince's meter last night at my home..... it was a fairly dark night at our place. The Milky Way was overhead about midnight when I took a reading,...
George - I used Vince's meter back in May at my home observatory and at the City of Rocks Star Party - no Moon but plenty of wind and dust. As I recall from...
Correct me if I'm wrong, but isn't the rule of thumb that you can get pretty good contrast imaging objects that have a surface brightness up to 2 magnitudes...
According to the directions that came with the meter, the units are mag/arcsec squared. It further states that a difference in 1 magnitude is defined to be a...
OK in laymen's terms what is the difference then between Upham (21.6 Magnitudes per square second of arc). And Bills home observatory was one magnitude...
Jerry.... I will have think more on this before addressing your questions. However, the website for the company that makes the meter has a lot of info. This...
George, The PDF didn't really answer the question, at least it wasn't obvious on a quick glance. I remember Samir Kharusi did an article on measuring sky...
Steve Thanks that is much easier to understand and for someone like me that is not a math Major or Physics Major It is understandable and even if not extremely...
I am a Physics Major, and reading that PDF made the hair on the back of my neck stand at attention ;-) Steve ... I am a Physics Major, and reading that PDF...
I started to look at the PDF but my eyes started spinning and I decided it was over my head. <;-) Jerry Gaber _____ From: ASLC_Imagers@yahoogroups.com...
Like I said, that article is a place to start. The website has a lot of stuff, but I could find nothing that said, if you get such and such a reading, you...

Dear Members: I really don't care for this part of the job, but here goes.... With great sadness I must let everyone know that our Society has lost another...

I finally got an opportunity to grab some photons while working through the learning curve of the 14" idiosyncrasies and the New AO8. I went for an easy target...
Just got one word for that shot... SWEET! You got everything playing well together, Jerry. Nice liitle spiral galaxy in the field too. Well done, Dave ... ...
Very nice Jerry! Do you think the AO8 unit made a difference? How long was your exposure for the guiding? I've read that is a big deal in getting the AO8 to...
Thanks Dave and George The .53 arc seconds per Pixel are according to the Sky 6. I missed a period. The corrections were with the AO8 and for luminosity I used...
Excellent shot Jerry. Looks like your getting it tuned in really quickly/ ss ... From: Jerry Gaber <stargate@...> Sent: Wednesday, August 06, 2008 1:38...
Very nice Jerry. The AO-8 is really a nice addition. KI _____ From: ASLC_Imagers@yahoogroups.com [mailto:ASLC_Imagers@yahoogroups.com] On Behalf Of Jerry...
Thanks Rich Perhaps I can if there is a bright guide star in the appropriate location. That is the big restriction but I am looking forward to getting the ones...
Jerry.... did you guide with both the mount and the AO8? George ... From: Jerry Gaber To: ASLC_Imagers@yahoogroups.com Sent: Wednesday, August 06, 2008 3:09 PM...
George I had it set up to do that but I don't think the mount ever needed a bump except for one time when My camera hit an eyepiece on my Pier and I went to ...
Thanks Steve, Steve, and Kirby The learning curve is a bit longer for us working stiffs than retired or jobless imagers but we still make progress and its nice...
