Description

Actually, this is my first image of M45 since i do astrophotography.

I'm afraid of big stars because something in my setup casts huge halos around big stars. As long as i can think im trying to get rid of these halos. Recently i upgraded from ZWO filters to the astronomic filters: It was an improvemend though, but the halos are still there, especially in the R and G channels.

I died serveral times during image processing trying to eliminate these halos. Its not getting better from here, even adding more lights does not make things better.
