Description

M101 from Corrales, NM with my new D5600 LifePixel modified DSLR, I seem to have better luck using ISO 400 (ISO 200 is the recommended ISO for maximum dynamic range).

This image is 28 subs of 230 seconds each, 9 darks, 30 flats and 50 bias. I would have gotten more subs but I mistakenly didn't think I needed my lens heaters and my guiding camera lost its guide star due to moisture. One of these days I'll learn,
