Andromeda Continued

 I've been taking more captures of Andromeda over the past few days, clouds allowing, and stacking them all together. Here's a comparison of 200 x 20s exposures (left) vs 100 x 20s exposures (right):

Next, I took all 200 exposures from the left image and added them to ten 2-minute exposures I took. I had hesitated to take these longer exposures because I was unsure if my alignment/tracking was good enough, but that was silly of me. The captures were just fine, round stars. Here's the composition of all the frames:

I think I'd like to get this up to about 4 hours of exposure time, hoping to get some of that captured tonight.
