I've been messing around with my HA filter lately, so I have some stuff to share. This is a photo of the Soul Nebula in through a 12nm Hydrogen Alpha filter using my 6" TPO Newtonian and ZWO ASI1600mm-c. I was planning on doing an HaRGB composite of this, but I think I'd rather save it either for the summer or when I get a better reflector. The reflector I have has crazy coma in the corners, even after being collimated and with a coma corrector. I'd rather get something brand new that has a decent reputation for doing well and I've seen the results from other people. I'm just not getting what I want with this scope as of right now, but overall, the image is still nice.
