imaging details on photos

Above : Seven 50 second exposures

There's not much good to say about the above photo. I did a lousy polar alignment but had good GOTO so I tried to get away with it. Didn't work. Ended up doing the wedge align about 15-20 minutes after the inital EQ North, followed by the required second EQ North and things got much better very quickly.

 

M82 - I took 3 different lengths of exposure and processed them each a little differently. I don't know which is better. I probably over-processed, but I'm still learning so...
