Description

REVISION - I cut back on the subs I used and limited it to only the best ones possible. This brought it down to just 35 frames, but cutting out the blurry ones really sharpened up the stars over all.

75x 60 second frames - Completely unguided, just a polar aligned mount. No Darks or Bias frames applied (yet).

The weather here in KY finally settled down for a decent night. This is the first time in almost three months since I've been out at my observing location. It's painfully obvious that my un-modded Canon 600D can't pick up Ha very well and that my refractor is achromatic. This I just a first run through with the current data I have - I think I'll end up going through each frame and keep only nearly perfect ones, as some coma and imperfect stars can be seen (Though I'm not sure if that is due to bad frames or the alignment process of Nebulosity 3).
