Description

Messier101  - the Pinwheel Galaxy.  Combination of data from 2019, 2022 and 2024, 2019 and 2022 data through Esprit150SX46 (and Espri100ASI1600 for Ha) 2024 data through Esprit100ASI294 and Esprit150QHY600.  Compared to my earlier attempts the much lower noise luminance data through the QHY camera has brought out M101s faint outer spiral arms.
