Fun astronomy adventure with Charles and Geoff.
About 7.5 hours of data from Cold Springs Cabin in late June 2025. Taken with the Orion 80ED, ZWO ASI294MC, AM5N mount.
One more image coming....

It's a question I'm pondering. My heq5pro mount guides around .8" to 1.5" after careful polar alignment. Supposedly, I can get that mostly closer to .5" to 1" with the mod.
I want to do it to prove dummy Rod Molise (the SCT police) and that EFT grump wrong. But maybe they're right.
Lest you think (or lest "I" think) I'm just criticizing Cloudynights, I stumbled across a forum post which I think typifies the problem with online communities:
ifi Zen Signature One DAC vs ifi Zen DAC V2 | Audio Science Review (ASR) Forum
I was just looking for info on cheaper DAC's and headphone amps and read this really bad moderator comment which mocked and advised someone to go basically "go away". Obviously no real attempt to "moderate" in a constructive manner. But I think it's typical of online communities. Conforming or "norming" is like a primary function of online communities. And I feel like it's quite destructive if one is interested in original thought and the respect of individual opinion. I understand there are times when one's individual opinion is at odds with a community but I feel like those times are really potential learning opportunities. Instead the true tribal qualities of a community get expressed over and over and over again. Conform to us or go away. Hierarchical violence.
It took two nights to get this image. This is about 5-6 hours of polishing of the 6 inch f/4.79 mirror. I started this like 7 years ago. There’s some surface roughness and I’m planning on switching to either red rouge or high quality cerium oxide for figuring. My knife edge is coming from the left side in a janky way. There also a kind of hole? I think.
Occasionally, I would see astigmatism but there's about 1.5 to 2 inches of vertical distance between the light and camera. So that could be test stand astigmatism. I probably should do 2-3 hours of general polishing next with the new polishing agent.
There are supposedly some really dark sites in Utah for astronomy.
