    Nice shot, Dave. I have been admiring your images for the A.L. Bright Nebula program and they have been very helpful to me as I work through the program myself via imaging. Most of my shots are just down-and-dirty ID photos - but after seeing your images, I have quite a long list that I will be going back to do *hours* of exposure instead of minutes!

    Thanks!

    Thanks, Anthony!

    An even better resource is the compilation by David M. Douglass, who has completed the list. You can find it here: http://www.az-dahut.net/ALBN-Data.htm
