Hello,
Just wanted to know if anyone can help me out with some incite into acquiring Flat frames.
Im using an Atik 383L mono my first real CCD camera.
I Mainly need help with how long to set exposure times.
I have read that its best to expose a flat at around 75% intensity of camera full well depth.
Specs i found state the full well depth for my atik 383 is 25,500 ADU so i need to reach around 17,000 ADU with my camera.
Question is how do i know what the ADU value is for an image?
I was thinking there must be a program or something that can determine the ADU level for me.
would appreciate any ideas
