Cassiopeia wide area with Canon 18-55mm kit lens
Trying to get some practice with acquisition and stacking with DSS. Also just beginning to learn processing. Unfortunately, I thought I had a full battery - but it was almost empty and I didn't bring a spare. So was only able to get 7 lights and 7 darks - so not much data - but pleasantly surprised to get M31 and Double Cluster in the shot.
Light frames 7x15" @ ISO3200
Dark frames 7x15" @ ISO3200
Bias frames 10
no flats
Just camera and tripod
35 degrees out, skies are typically between 21 and 21.4 mag/arcsec^

If my processing skills were better this might have been a pretty good shot.
Comments, criticisms, suggestions are most welcome!
