Description

This is my first attempt of using H-Alpha exposures to improve a DSLR photograph. Did I hear somebody say: "But H-Alpha is useless with a DSLR, because on the Bayer matrix, only every 4th pixel is red"? Well......

Stack of 70 exposures of 180 seconds each at f/4 and ISO 1600 for the RGB data plus 56 frames of the same exposure time and ISO 3200 using a 7nm H-Alpha filter.

Taken on September 19th and October 19th 2020 in rural Upper Austria with a Nikon D750 and a Skywatcher Espirt 100 (reduced to 412mm f/4 unsing a Ricciardi reducer). Tracking with Skywatcher EQ6-R, Autoguiding with MGEN-3. Processed with Astro Pixel Proxessor, Starnet++ and Photoshop.
