Description

This is the last m106 - combination of 2022 and 2023 images. Setup is the almost the same (Newton 250 F 3.9 Orion USA, different coma corrector, same camera (QHY268M) but different filter (Astronomik ha 12nm for 2023)), but background in 2023 image was very bad. This combination seems that has improved background. Still not perfect but better. Registration and sum with Astroart 8. Mask and deconvultion with Astroart 8
