Description

Tricky to capture the bright and dark areas at ones:

The Atik cam mounted on a 12" telescope get's too much light from the bright areas of the moon,
especially when missing a grey filter. And total over-exposure was not my desire.

My work-around solution was this:

Atik exposure time at lowest setting (0.0001 s) and dobson tube cover plate installed.
Only sun mode hole open. Unfortunate side effect : much less contrast.
