Description

This is a mosaic of 3 panels RGB comprising a stack of 120 exposures of 2 minutes each. Taken during 5 nights in 2018 and 2019 in rural Upper Austria with a Nikon D750 and a 135mm Sigma Art lens at f/3.5 and ISO 1600.

In November and December 2020 3 hours of H-Alpha data (45x 4 minutes at f/2.8 and ISO3200) were added for each panel. An Astronomik 12nm H-Alpha clip-in filter for Nikon DSLR was used. Tracking with Astrotrac; processed with Astro Pixel Processor, Starnet++ and Photoshop.
