Beautiful image Bernard. It doesn't look like you had any problems with the processing! Great detail and color. This one is on my list and I hope when I get to...
Messier 74 is a face-on spiral galaxy in the constellation Pisces. It is at a distance of about 32 million light-years away from Earth. The galaxy contains two...
Well done Jeff! Ron ... From: Jeff Armstrong To: ccd-newastro@yahoogroups.com ; starlightxpress@yahoogroups.com ; CelestronCGEM@yahoogroups.com Sent:...
Yes. This galaxy has been difficult for me, too. I've shot it eight times over the last several years. It always looks to me like it's a bit out-of-focus,...
Sorry, this is not completely on target, but I'm sure that many folks here deal with it: The cold weather seems to have a high toll on my cables. So far, I...
Actually, it's completely on topic for the group. A few questions: * What do you mean when you say "broke the cable?" Did it literally snap, or if not, what...
Thanks for the quick reply Ron! ... At the end of an imaging session, when I move all my equipment back in, the cables are VERY stiff. I try not to bend them...
The cables on the ground might actually be warmer than those hanging in the air, due to the way heat loss works. (You can radiate more heat than you can...
Happy New Year! During a recent trip to Rodeo, NM, I captured 5, 10 minute images of the Horsehead Nebula before the clouds rolled in. Aquisition details are...
By that I mean fastest relative motion. C/2012 K5 LINEAR was racing through Taurus on December 31st at 13.89 arc seconds per minute, relative to the star...
What elevation was this taken at? Most astronomy UV imaging is done at shorter wavelengths than 320nm, and given how the atmosphere blocks those wavelengths,...
Steven works from Bacchus Marsh, Vic Australia, elevation 100m. The exposure was 120min with his Tak BRC 250 (Ritchie Chretien with Baker flattener/corrector...

I agree Dennis. Well done! Ron ... From: Stan To: ccd-newastro@yahoogroups.com Sent: Sunday, January 06, 2013 8:53 AM Subject: [ccd-newastro] Re: Fastest Comet...
Hi, I was wondering if I could get some help with an issue I have been having for the past month or so. I have an ST-8300 with the OAG-8300 and STi guide ...
The first thing to check with angle-specific guiding issues is cabling. It could be a snag, a cable could be stretching to its limit, it could be caught in a...
Hi all I have got a SBIG ST2000XM and would like to know what is the best filter to use in an urban area. Boas Festas / Season's Greetings /Frohe Festtage ...
If I am reading the guide log correctly it looks like there may have been no guiding at all. Check your signal connections and confirm that the software is...
Stan, It was definitely guiding. You can see the guide corrections being issued after the v-offset jumps from near 0 to -27. The long string of 0.40 are the...
Hi Bernard, Check your settings for agressivenes and min and max move for your DEC. You are detecting errors but not issuing correction commands of any...
... So the main issue is what moved the mount by such a large jump, especially if it happens repeatedly. Ron's suggestion of cable drag/snag is a possible...
Hi All, I just wanted to take a minute to introduce myself. I'm an amatuer Scope guy, just starting out in the astro photography world, I've had very little...
Terry, Welcome aboard. I think you will find that this is a very helpful group, and you should glean a lot of knowledge from them. They are very helpful, even...
Keep in mind even if your Min Move settings are correct Max Move set too low will limit the amount of correction. Try using the Default Max Move then, as...
