Very low SNR contribution from Observations
Hi Phil - and Merry Christmas and Happy New Year to you too!

That sure sounds like a good theory and thanks for taking the time to think about it. I went back to the project and changed the goal to "Main Extent and Arms," clicked Done, then re-opened the project. The SNR results didn't change for any of the existing observations.

I happened to capture 32 more frames of this last night so I added that observation, and it showed up with an SNR of 1.

Maybe that's the reality of this object - it's just so dim that even though it looks to like I'll get an "OK" image with maybe 20 hours of data, the SNR is just very low. In that case, I should probably switch my goal to hours of exposure, or re-adjust my thinking about what an acceptable total SNR should be.
