These images of M51 and M104 were taken with a cooled greyscale quickcam and a 10 inch LX200 with a Meade f/3.3 focal reducer at the Highlands Stargaze 2000 in Florida on 03/04/00.
For image on left: Stacked 10 images of 60 seconds exposure each using DarkGen software by Dave Allmon. A median of three dark frames were subtracted using the same program and the Median Sum setting was used for the stacking method.
First image of M104: Stacked 14 images of 60 seconds exposure each. Clearly I will have to take more exposures and try longer durations.
