One bad, and one not quite so bad picture...

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.
