Hi All,

Not sure if this has been discussed elsewhere. I am thinking of experimenting with using an IMX585 sensor camera with my Celestron C8 at native (or even 0.7x reduced) focal length.

I understand this is grossly oversampled. Has anyone tried this? Or with another OTA of similar or longer focal length?

For context - this will be deep sky work.

Thoughts?

Thanks, Cheers and, CS

A guy local to me has just recently started imaging primarily with a QHY Minicam8 and a Celestron EdgeHD 925… His results are stunning, especially on nights of good/great seeing!

I’ve used a 585 on an 8” SCT. reduced and at prime with good results. A lot of people are afraid of over-sampling but if your seeing is good enough it can pay off. If you’re looking to make images where you can’t see the galaxy because of the IFN, it’s not going to be the best approach but if you like detail, give it a go.
