This is my second attempt at this object. The first one is also published here, but I wasn't happy with the guiding quality on that one. I had to capture two sessions because the weather didn't allow for a long window, so I didn't frame it quite right, and after stacking there was a large crop—26 megapixels turned into 18 megapixels.

The preview looks decent, except for the overly blue stars. However, at full size, the stars are disappointing with their flat, blocky profile. The noise is also quite noticeable.
