I had no idea such group existed

I just found it today when I decided to look for one. I had thought about asking if the mailing list had a facebook counterpart, but then supposed that if it did, I would have heard of it by now. On Mon, Aug 1, 2011 at 8:24 PM, Jorge Gutierrez <gotfoxx@hotmail.com> wrote:

Just got back from Echo a little while ago. Pretty good skies, no clouds but the usual amount of light pollution all around. It was worth it tho, when I got back to SLC it was pretty cloudy. Not my favorite spot, but it beats sittin around watching Netflix. On Mon, Aug 1, 2011 at 8:35 PM, Chrismo <djchrismo@gmail.com> wrote:

Glad things went well at Echo. I've spent most of the night chasing a very faint little minor planet across the sky. It's below mag 19 so I guess I should be happy that I'm able to image it at all. But it's so faint on the images I'm having trouble measuring it. Time for a break. patrick
This is kind of disappointing to hear Patrick. One of the reasons I'm saving up for a 14" edge HD is that I thought the limiting CCD magnitude would be more like magnitude 20. Clear skies, Dale.

Wouldn't light pollution affect your ability to see down to mag 19 or 20? -- Joe ________________________________ From: Dale Hooper <Dale.Hooper@sdl.usu.edu> To: Utah Astronomy <utah-astronomy@mailman.xmission.com> Sent: Wednesday, August 3, 2011 2:06 PM Subject: Re: [Utah-astronomy] anyone going out tonight?

Hi Dale, 20 is no problem. I've gone deeper than that before. The run I was doing the other night involved short (30 and 60 second) exposures. When working minor planets, especially NEOs like the other night, exposures need to be kept short so the target remains a point source and not a streak.

Hi Patrick, That makes me feel much better. With my 10" scope, as Joe mentioned, depending on seeing, the moon, etc. my limiting magnitude for minor planet astrometry (even with a 6 minute exp) is just shy of mag. 19. It sounds like I can do a lot better with the 14". Now I just have to save up for it. BTW, for anyone interested the Edge HD's are discounted 10% during August! (That's a $1000 savings for the 14" Edge HD on a CGE Pro mount). But, I'm afraid that isn't long enough to help me. Thanks & clear skies, Dale. P.S. When I saw your message it made me a bit nervous so I looked for a limiting mag. calculator online. The one I tried was "visual" only. Using typical max pupil size, etc. it said that the *best* I could do with a 40" scope or 4000" scope was magnitude 17.5. Thank goodness for CCDs.
