In my integrated image of the horsehead nebula, I notice steps pattern on the right side (attached).

The integration included two sessions (60s and 120s).

A meridian flip was done during the 120s session.

I suspect the the pattern is somehow related to a problem in normalization.

Help with the issue will be much appreciated.

Thanks

Ofer

Mmm, I guess so, but the image doesn't look right either. It shouldn't be so dark nor over-saturated. Was this done to show the stepping? Could you describe what you do for calibration, your procedure, software used etc?

Sorry. the image was processed to highlight the stepping.

now I see that the stepping happened when I rotated the image in APP.

I attach the non-processed image and the rotated one.

Oh interesting, I'll ask Mabula if that would make sense, thanks for showing!
