While I was observing the moon I decided to quickly step by at Saturn. The image got better than I expected and so I am sharing it here 🙂 The Cassini Division (the thin black line in the ring) is clearly visible even at this low image resolution. The raw data was recorded with a DMK31AU03.AS camera and then post-processed with Registax.
Clear skies!

The DMK31AU03.AS camera only has a resolution of 1024 x 768 pixel. To create larger images one can record multiple regions after another (a mosaic) and then put them together to one big image. This can for example be simplified using the “EQ6 Mosaic” tool.

The Image Source DMK31 does not work with Windows 8.1and Intel USB3.0 host controller. This is what I had to find out recently….
But lets start from the beginning: Recently I bought a new notebook with USB3.0 ports. In general I thought USB2.0 devices should be back-compatible to USB3.0. However for the DMK31AU03.AS this assumption did not hold.

Actually this motif – the Great Orion Nebula (M42) – was one of the first nebula I have ever tried since starting with astrophotography. I was already quite satisfied with the first result (maybe because I didn’t know better :)). Tonight I decided to give it another try. Personally I think it is much better than the last one. The image is also available in full resolution.

Tonight I imaged Jupiter and some of his moons – a relatively bright spot in the sky – with my DMK31AU03.AS “The Image Source” camera. This was the first time I saw Jupiter through a telescope. Fantastic! First I could not believe that the other bright spots around are some of his moons!
