OK so what is causing the arcs of light in the photo? Its consistent between frames (LRGB) but varies by target in the sky.
This is a Astro Tech AT65EDF Quadruplet and a ST8300M
Ideas? I think its obvious reflections but off of what?

Wat.
Jeff, I thought for sure it was the differential mitobia. LOL that was a good one.
Conor - you meant to say: There was an unbaffled/unmatted differential mitobia inside the focuser...., but s'ok, we knew that.
I diagnosed the exact issue with another guy recently. There was an unbaffled/unmatted surface inside the focuser. It caused the exact same class of reflections.
It's that mitobia stuff, I've seen it before and it's nasty!
It's the television tripartite Narrow-Wave EM reflection in the 600Megaspotz region causing differential mitobia on your CCD. Quite obvious if you look at the curves.
Not sure on the alien stuff :) It does have a dew shield that extends -34"
I think it's aliens doing a high speed race above your house, be careful man, you don't want to let them know you are watching.
Looks like lense flaring caused by an outside light source. The same light source would be hitting it at different angles when you move to a new DSO.
If not from the front then from the side.....
My AT80 had a screw on mount plate which I took off. I covered that empty hole with tape.
Just guessing.... Did I win!!!!??? :)
