DF9CY Christoph Petermann - Astrophotography

Here are a few Jupter images I took with my DMK21 camera. Jupiter was still very low in the sky (ca 20° elevation at the end of the session) and seeing was very very bad. I was not able to get something useful at higher magnifications. This was also the first time I have used the DMK21 camera for imaging an astronomical target.

I have made 20 videos. Only three of them were good enough to be processed.

I tried higher magnification here. This image is reduced in size again by 50%.
