M33 a face on galaxy

M33 a face on galaxy
M33 - The Pinwheel Galaxy is the second brightest galaxy we can see and is located near the Andromeda Galaxy.

The photo was taken through an 8" telescope using a Paramount ME mount to provide excellent tracking. The camera was an SBIG ST2000 cooled CCD unit. I shot five 10 minute exposures with red, blue, and green filters which totals three 50 minute exposures and then combined them after subtracting dark frames. The camera was cooled to -25 C. to minimize thermal noise from the CCD chip. The image processing was done in MaxIm DL, with some finish up work in Photoshop. In my opinion the most important part of the process is the mount to be able to track effectively and get consistent images.

Léon Régel has particularly liked this photo
