Description

This was a test shot of a lot of things: Shooting separate RGB via my mono ASI294MM using my RC8 with the CCDT67 0.67X reducer.

What I failed to do was dither when I shot this and it shows. Ugh.

There's more data in the core than shown here, but since this was a test shot I'm too lazy to go get it.
