Description

M101 from my backyard.

This is the second go on processing the data. The first version was pleasing to me at first.

After having spent a lot of time watching Adam Block’s Fundamentals an workflows, I guess my view has changed and I’ve gotten even more critical about my processing.

I still have a long way to go but I’m enjoying the journey.
