Description

Pixinsight's WBPP rejected 87 out of 100 images - never happened before and I haven't a clue why. I Blinked all the images (pre & post processed) everything looked great. I did a lot of Googling to no avail. So I stacked all 100 images and calibrated files in ASTAP and everything worked fine. I rolled the ASTAP result into Pixinsight and processed it from there. I thought I had my Optolong L-Extreme in the filter drawer - nope - it was the Optolong L-Enhance. So  my OIII data is lacking. That won't happen again.
