Hi all.

I have been out of the game for a while but want to get back into astro imaging..

Can anyone suggest what the best focal length and F-Ratio are for imaging various Deep sky objects and the recommended exposure times...
Does any know of such a guide that may exist..?
Also same question for planetary imaging.

My armamentarium is as follows:

Hep5 pro
WO Megres ED 110mm
GSO RC8
Celestron CPC 925
QHY5 -L
QHY8 single shot colour
QSI 683wsg-8
Imaging source DMK 41BF02

Any help or advise would be really appreciated.

Thanks

Regards

John
