CCD Imaging Tutorial
Astrophotography CCD Imaging Topics
There is quite a steep learning curve when first using an astronomical CCD
camera. You should not be disappointed if your early attempts do not turn out
like Hubble pictures! I have made some notes to try and summarise my experience
and these are presented here. They are the result of
my personal experience and research into the subject during the last couple of
years. If you have any comments Let me know!
