Description

This is the Alnitak general neighborhood in (mostly) narrowband. I had to create a synthetic Oxygen channel, as my Oiii filter not only had a HUGE, BRIGHT internal reflection around Alnitak, but combined with the ASI1600 microlensing artifacts, was unusable. Since there is not a lot of Oxygen in this region, I created a synthetic Oxygen channel by taking the average of Blue and Green. 

These channels were combined using the NBColourMapper script in Pixinsight. Further tweaking in curves was used to accentuate the Sii.
