Hi all- I had to jump in on this one. I'm Jerry's business partner, John Wunderlin.

You can't use Jupiter very well to focus- I saw the same thing in my testing- it has to be a pinpoint of light, though on the Russian forum I see someone was able to use lights on a distant building in daylight that worked pretty well.

The other item related to this is that collimation affects the pattern. If your collimation is off, the pattern is distorted and my not provide proper focus, though if your collimation is off, you'll have additional imaging issues
