M76, the Little Dumbbell Nebula
I clearly need more data for this one, but this is part of my learning curve for shooting through the Celestron Edge HD 925 with the Nikon D5100. I used a light pollution filter and was shooting at ISO 1600. This is a stack of 30 exposures that were around 55 s in length at a focal length of 2200 mm. I reduced the size of the final image substantially because it was so noisy.
Preprocessing, registration, stacking, and initial processing were done in PixInsight; final touches in Photoshop.
