Title: Haloes Around Stars
Post by: Farzad_k on 2017 September 16 20:13:41

Hi folks.

The image I am working on was captured in highly polluted skies and under poor seeing conditions - but we gotta practice, right?

I don't know what could be causing the haloing effect in the attached. The target was the NGC 7000. Thanks for any feedback.

Hi Farzad!

Usually you get halos of this kind when one combine (L)RGB with the module LRGBCombination AND "Chromatic Noise Reduction" is checked(!).

Uncheck this option and try it again.

Best regards!
