This is a reflection nebula just above the star Sadr. You can find it in the widefield shots if you look up to the left of Sadr at about a 45 degree angle. There's a dark expanse and then two faint blue smudges. ;) It's one of the first longer integration images with my AT115EDT refractor. I wanted to find something with a suitable field of view that was also visible from my location. I hadn't seen this imaged very much, so I chose this. It may be difficult to see, there's a slight orange hue on the corners that didn't get calibrated out properly.
Taken with my AT115EDT, ASI 183MC, and GEM28 mount
Revised image of above data
