Signal to Noise Comparasion

SBIG STL11000 CCD vs Canon 5D DSLR

The rollover image above was made using images captured within minutes of each other on a 14.25"

telescope. The SBIG CCD image comprised 30 second dark subtracted RG&B images, the Canon 5D again was a 30 second

exposure at an ISO of 1600, in camera noise reduction ON. No Flat fields were applied to either image.

Both images were gamma scaled to equivalent background noise levels.
