Description

The weather recently has not been conducive for image capture, with a mix of wind/terrible seeing and/or high clouds. This has limited my last two capture's exposure times.

This is 12 hours on M81 and M82 with Arp's Loop and other galactic cirrus as I recently learned the "pros" call it. (Rather than "Integrated Flux Nebula".)

It was challenging to pull down the noise in the IFN/cirrus. I made an attempt to learn some noise reduction in PI and gave up. Every time I try to understand a new procedure in PI I end up being reminded of this: Turbo Encabulator

Description: There were several things bothering me about the original version of this, not the least of which was the mottled appearance of the IFN from over stretching and over noise reducing it. I have only 12 hours and the IFN is exceptionally faint, so I tried to respect that more in this iteration. I am also going through fits and starts with learning to use Pixinsight more, so I was working through a new flow from Rogello Bernal Andreo's book, "Mastering Pixinsight" using this data. This is a "ground up" reprocess utilizing more PI than ever before, (for me), but after too much time in the deep end, I did swim back to my happy place in PS to finish up.
