I got no darks/bias for the temp it's running at tonight either. And the t-threaded oag will have to go looking at that flat
Uh-oh... I was hoping to test my RC8 + Canon 5DmkII. This doesn't bode well!
Perhaps I'm mistaken, but I thought that RCs are meant to suffer from field curvature rather than coma...?
It's definitely curved but it looks like coma to me. Here's a ccdinspector 3D plot of the Lum in that M20 shot.
Other plots tell me to check tilt and collmination as well.

The problem was never plugging the oag in, it was the size of the hole in the middle.
I'll need an atik or sx oag to get the size up but it looks like it needs a flattener as well so they might not fit in the path length.
I'll have to do some googling
An adapter for the FS-60 should be here next week so except rain
