M61
M61 (NGC 4303, UGC 7420 and many others) is a seyfert 2 galaxy (https://en.wikipedia.org/wiki/Seyfert_galaxy#Type_II_Seyfert_galaxies) located approximately 54 million light-years away in Virgo.
NGC 4301 (NGC 4303A, UGC 7439 and others) is the somewhat odd spiral at the top left.
NGC 4292 (UGC 7404 and others) is spiral at the top right. This one reminds me of M77 or M94 – both galaxies with a bright core and a faint ring of outer arms.
Luminance – 8x600s – 80 minutes – binned 1x1
RGB – 8x600s – 80 minutes each – binned 1x1
320 minutes total exposure – 5 hours 20 minutes
Imaged March 17th and April 13th, 2021 and March 1st and April 6th, 2022 at the El Sauce Observatory (Rio Hurtado, Chile) with a FLI PL 9000 on a PlaneWave CDK24 at f/6.5 3974 mm.
