About this image

A total of 42 hours of exposure on this much imaged object. I avoided Alnitak, but the glare from it can be seen causing some artistically pleasing rays of light from lower left.

Taken from my remote scope in southern Spain., Details are here: http://www.astro-sharp.com/2021/10/23/my-new-remote-setup-in-spain/

Fully calibrated and processed in PixInsight.
