Description

A M42 center mixed Luminance, SII, Ha, OIII narrowband picture.

Tried one more time to do the frame processing from scratch and 10 hours later I ended up with this version2.

Manually quality sorted frames were stacked like this:

Lum: 68x1sec. SII: 32x10sec+45x30sec. Ha: 35x10sec+30x30sec. OIII: 83x5sec+26x30sec.

More details about the raw matrial can be shown upon request/if needed, thanks a lot.

My home build observatory is placed in my front yard/in the "red light" polution zone, have a look here,
