Scope Used: 12" L200 at F/6.3
Camera: Canon 10D @ prime focus
3, 4min unguided bulbed images where stacked, aligned, and averaged in Photoshop.
I applied a gradient radial mask for helping with a small amount of viginetting caused by the reducer @ 6.3.
I then masked a single 30 second image to help resolve the central core a little better.
