Description

I'm really pleased with how much detail I was able to pull out of the knots in the Bubble Nebula with only a 120mm refractor (0.76"/px). I think it holds up well against images from larger scopes aside from star size. I threw out a decent amount of Ha data, heavily favoring low FWHM. The FOV is much bigger but I preferred a small crop (0.22 deg) to show more detail, and it lends itself to a higher contrast look that brings out the pillars as well.
C&C welcome!
