Description

M51 Whirlpool Galaxy in Canis Venatici
Recorded 4-6,4-7, 2022 Camino Cerrito Albuquerque, NM
GSO 200mmm f/8 Ritchey-Chretien telescope / UVIR filter / AT2FF field corrector / ASI294MC Pro camera
143 subs x 120s 120 gain (4.8 hr integrated exposure)
Reprocessed 2-25-2023 in Siril v1.2 (photocolorcorrection, bkg extraction)/ PI (BlurXterminator, General Hyperbolic stretch, NoiseXterminator).  Note: I have found that Siril's color correction and background correction are easier, faster to use, but PI's BlurXterminator and Generalized Hyperbolic Stretch give far superior results.
