M81/NGC 3031 - Bode's Galaxy
Date Taken: 3/9/08, 2/24/09
Scope: 12" LX200R @ f/6.5
Camera: Hutech-Modified Canon 30D
Exposure:
3/9/08: 107 x 3 minutes @ 800 ISO, no LPS
2/24/09: 31 x 8 minutes @ 800 ISO, plus IDAS LPS
This is actually a combination of the previous two photos of M81. Since I didn't use the LPS filter on one, so I had to stack each set separately, then balance the histograms in PixInsight LE, and then stack the two balanced results. I also had to crop it quite a bit because of the difference in camera orientation between the two photos.
