ASI 290mm or 120mms for planetary use with a C9.25?

Hi all I posted the same query in the imaging forum but got no response.

Which monochrome cam is best suited for use with a Celestron C9.25?

The ASI 290 mm or 120mms, or other camera?

This will be for high res RGB planetary imaging and not for DSO’s.

I read a review where it said the 290mm would be overkill for a C9.25 so I wanted to hear from the experts here on which camera is best.

thanks

Hi there

ASI290MM and ASI120MMS can works well with a C9.25.

if F30 is limit of ASI120MMS, you can use F25 for ASI290MM.

To avoid over sample problem.

If do that, the performance of both camera, I believe ASI290MM will be better.

Thanks Sam for your reply.

Done deal then, I will pick up the 290mm based on your feedback for this Mars apparition.

Cheers!

That's great!
