Theo Ramakers has just submitted the following images (click to zoom):
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!
