Techno Stuff: 8/18/07 Camera: ATK-16hr, Imaging Scope: Megrez 80mm APO at F/6, mounted on LX90 8" SCT, Ha 6nm, 76 minutes total with two 30 min subs and one 16 min sub (interupted due to clouds), binning 1x1, Autoguided with DSI Pro and PHDGuide from LX90, No Darks, Processed with CCDStack, Photoshop CS2 and PixInsight

Notes: Seldom imaged by amateur astronomers, this is a very faint emission nebula in the constellation Cygnus. This is located due east of the popular Crescent Nebula. Sh-104 is viewed by professional astronomers as a good illustration of the "collect and collapse" model of star formation triggered by the rapid expansion of a Helium II region.

Techno Stuff: 8/26/07 Camera: ATK-16hr, Imaging Scope: Megrez 80mm APO at F/6, mounted on LX90 8" SCT, Ha 6nm 140 minutes total with 20 min subs binning 1x1, Autoguided with Q-Guide and PHDGuide from LX90, No Darks, Processed with CCDStack and Photoshop CS2 and PixInsight

Notes: I tried to keep the amount of processing down on this one because the stacked image looked so good. This was taken on a clear calm night just after about 2 weeks of rain.
