Description

2021 update of one of my favorite targets. I'm really happy with the detail of this target that is strong across all 3 channels.

I took advantage of 2 cold nights to image at -30C and still had to toss a bunch of data, but really happy to see the improvement over my version from last year.

This is also my first session after replacing the Stellarvue 0.8x FFFR with the Hotech flattener (no reducer). I see round stars out to the edge with this setup.
