Description

C&C very welcome, I had trouble processing this one well. I simply need more data, but the weather isn't going to allow that for the next week at least.

Very hard to balance getting the faint HA without overblowing the center, or raising the noise too far.

All subs were OSC from the Optolong L-eNhance Pro. It's sub-optimal for Ha at F/2.
