Thank you all for your replies.

The Atik 460 is cooled to -5 c is that OK ?

I will read through the BASS project user guide to see if I can create a master dark frame.

I assume the same procedure applies to flats and that I need to take a set say 10 after each observing run. ?

My Lhires II has a built in flat lamp.

Andy,

Thank you for you step by step reply.

This information does not appear to be available from Celestron when looking at the C14 specs or anywhere else.
