It's been a while since I posted on this particular forum. Moving and starting a new job cut down on my imaging time badly during the past two years. I am finally getting some decent integration time, so it's good to have a galaxy image to share.
NGC 5371 (also called NGC 5390) is an 11th magnitude galaxy in the constellation Canes Venatici near the Hickson 68 group. With apparent dimensions of 4.0' x 2.5', it is appropriate for imaging at larger focal lengths. NGC 5371 is a type SBc barred spiral, meaning it has loosely bound arms. There are a lot of faint fuzzies in this part of the sky, which add to the appeal of this target.
This image captures the fading Supernova 2020bio, which was initially discovered in late January 2020 and reached magnitude 16 shortly thereafter. The data for this image were acquired on May 13, 20, and 21 of 2020, and the supernova had faded considerably. The location of the supernova is identified in the "B" revision on the Astrobin page.
Part of the luminance data for this image and all of the RGB data were obtained from my back yard (Bortle 5), while the rest of the luminance subs were obtained from a good dark site (Bortle 3).
Overall, I am happy with the way this one turned out. It is not so easy to capture colors in this galaxy, judging by most of the images I have seen. I took the RGB data from home with light pollution, so I was not expecting much, but the colors came out just fine.
