Jupiter taken in october 2012, and Jupiter in september 2011. The first with dbk21 and the second with NexImager. I think I have problems with both collimation (C9.25) and bad seeing on the first picture (since the dbk should be a better camera than NexImager). I post these pictures to show that some of us still has some room for improvement :(

Hey Rnulf, no sad face needed. The second image is pretty good, certainly for a Neximage. It shows your processing is OK, and collimation can't be too bad.

Re the DBK, I saw another post of yours where you mentioned you have the gamma at 50% and the debayer on. Go to 100% gamma and you will get much better results with the DBK. Also, turning off debayer in the camera will allow you to go 60fps, which is a help in poorer seeing (I use it like this all the time ;)).

Good luck!

I'd agree that the first one looks like it was shot in bad seeing. Also. allow the OTA to cool for at least 3 hrs before bothering to gather data..If collimation was not right, it certainly got fixed, or was better in the second image; nice result.
