IC 405, IC 410 and friends @ Bicolor

The settings in APP are very helpful in order to develop narrowband recordings so well with a DSLR. Many thanks to Mabula !!!

The open star clusters and galactic nebulae in the constellation Auriga are interesting for many focal lengths. Whether as a detail or an overview, there is always a lot to see. Above left the "pancake" is an object from the Sharpless catalog and has the number SH2-232. I was amazed that this Nebula was so clearly visible in the short exposures.

There was a lot of water in the air during the night. Was delighted with the fine details.

The green channel had a very good signal from the H-alpha image taken with the color DSLR. The data made it possible to create a bicolor.

- easy crop
