PROBLEMS calibrating data with APP - 3nm Ha
I'm a super fan of APP, and recommended to all my hobby collegues.
That said, I'm experimenting a problem with my first light of the ASI2600MM+SigmaArt85mm1.4 (stopped down at f/4). ANTLIA 3nm Ha filter. GAIN 100 BIN1.
-Lights, flats, darkflats, darks applyed.
I just did the following settings: all by deffault. I only changed this:
-COSMETIC CORRECTION (because you recommended it)
I see an awfull donuts around the stars (not the bright, but the medium).
Thanks for your help!!
@aleix Hi! What version of APP are you using? Because I have troubles locating the COSMIC CORRECTION option that you mention. If you are not using 1.082 or 1.083-beta2, can you please try with 1.083-beta2 with all defaults and see if that solves the issue?
2) COSMETIC CORRECTION
Lastest versio 1.082
