I purchased a DMK 21AU04.AS two month ago. In my quest to try to find the best sample ratio for Jupiter of my Celestron CPC925 and the camera, I ran a test of Jupiter using no barlow and a 2x barlow with different nose piece extensions. Here the results of the red images only.

Also [above is] one IRGB image taken one day earlier showing the GRS.

Maybe some other C9.25 and DMK 21AU04.AS users can benefit from this test.

Thank you Theo for your great contribution!
