The Deep Sky Collective just released their newest photo. which resulted in over 525h of total combined exposure time (of which I contributed over 42h)!

Shown is CasA*, a supernova remnant that is very very faint and required a lot of work to get all of that depth with amateur telescopes. The image is a narrow band image in the SHO palette, meaning red hues are Sulfur (S-II), green hues are Hydrogen (H-alpha) and blue hues are Oxygen (O-III)
