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.

The Flaming Star nebula (IC405) is an emission and a reflection nebula in constellation Auriga. The nebula is approximately 1500 ly. away from earth. The final image is a combination of 37 different frames with an overall exposure time of almost 4 hours (including dark frames).
The image also available in full resolution.

The Flame Nebula (NGC2024) is an emission nebula in constellation Orion. Looking at the image you can imagine where the name is coming from. The bright star right to the “flame” is called Alnitak, a hot blue super giant. At the bottom left is another object – the emission and reflection nebula NGC 2023. This is quite “close” to the Horsehead nebula. The blue spot in the center of the image is a reflex caused by the bright star.
The image is also available in full resolution.
