California

[true carbon]

What do you all think of my 63.5 hour California Nebula gathered over 2 years from my backyard. Fra400 w/ reducer at 280mm focal length, Antlia 3nm S,H,O filters and asi2600mm

For 63hrs I bet there's a lot to pull out, seems to be solid data.

The immediate thing I notice is this transition from Ha/SII to OIII

Hard cutoff, which is unnatural. I see it in other areas too. I would avoid using masks to do local color adjustments.

Very nice

btw I barely got any signal in o3 when I tried this target, how did you get this nice blue?
