Starfields in Camelopardalis

 I'm still learning how to use the new mount appropriately, and also how to process the huge amounts of data produced in a night. Yesterday evening, I went out to try and capture the heart and soul nebulae, despite my camera equipment being rather poorly suited to do so and the seeing conditions being ranked "poor" by cleardarksy. After completing alignment, I let the mount point where it thought the nebulae were, and... it missed. 

I ended up with a starfield image containing the Jolly Roger open cluster (lower left), and a lot of stars.

The image here is based just on the light frames, exposed for 45 seconds at 3200ISO, with a focal length of 120mm. There were 169 lights, of which around 150 were used. I also took dark, flat, and bias frames, and am working on incorporating them into the stack. If you look closely, you'll see a prominent dust spot which these calibration frames should help eliminate. 

 In the meantime, here's a picture of a goddamn lot of stars:
