Description

This image is my third go at M81 during the past 3-years that I've become re-involved in this hobby.  I didn't post to Astrobin my 2021 image of M81, which was taken with a Nikon D5600 and processed in StarTools.  However, I did post last year's LRGB capture with what was, at the time, my new ASI 294MM.  This year's image reflects the addition of an H-alpha filter, as well as increased processing experience with Pixinsight.  Nights of good seeing were few and far between in February, with this image captured  the nights of January 23rd, 24th and February 20th.
