Still tinkering with the new FSQ plus 645 reducer combination.
I'm noticing on nights of excellent seeing the extreme corners of NB images show some coma, but meh...I guess that's the price of the 5 degree field.

I was surprised to see the "fickle finger" (near the keyhole) actually resolved at this image scale. I'd expect the full field would probably make a nice 16x20 print.
