Thanks Carole and good eye on the contrail. -Doug

Very simple shot but it works extremely well Doug. I see the Big Dipper plus about 17 other faint stars, and is that a contrail on the left above the left star? Great shot and perfect for the challenge! CJ

Thanks to all. I'm on the edge of the city limits. We like to go camping up by Leadville which is over 10,000 feet above sea level. There are so many more stars up there that you can hardly find the big dipper in the maze. You wouldn't think that a couple miles are significant but they are. -Doug

yeah, on my work monitor this was not good so I waited til I got home. I can't believe the diffference. I also can't believe the clear sky. Amazing. Penny Street

Down here near sea level, the big dipper seems much smaller of I can see it at all which is only at the beach in south Jersey. I'm amazed at the difference the CO mountains makes in size as well as clarity. -tv

Rod It's amazing to see how much the stars move in just 30sec a. Being able to see the tree is a nice touch. At least you got your tripod out the house.

Same as Kiki my sky just won't get this dark this time of year- maybe almost after midnight. I think the exposure is good Doug as I can see 12 stars quite clearly as well as the tree and if I look very closely I can see another 8 or so stars. I guess you are far enough away from Denver to not be so effected by the city light? ~Brent

I see 10 other stars here. -k2

It looks like the dipper to me - the stars are fairly clear - but no other star is visible -Debi

My monitors are good on dark areas, I see it all, but the tree does appear to be darker now than when I looked at this first time. Night-editing can be tricky. Our eyes adjust so well to the lack of light, and likewise to daylight. But go from daylight to a dark room and you won't see much for a while, it takes ever longer to adjust to our "night sight" mode the older we grow. Some "editing monitors" adjust according to available light in the room, but I don't know how well that feature actually works. Perhaps it just fools the editor and no-one else lol -k2

Thanks k2. I posted this from home last night and it looked fine. Now this morning on my work monitor I can hardly see anything. The tree on the lower left as well as a couple dozen other stars were all clearly visible from home. Makes me wonder what everyone else is seeing. -Doug

Nice dipper :) It looks completely different from my latitude, but I can't see any stars from here this time of the year - the nights are too bright. Only one or two planets are still visible from town around midnight. -k2

Well, at least there are no dust spots and only minimal noise. -Doug
