Description

Experimented with using and not using flats (taken at the same focus). Turns out that the majority of my vignetting came from being out of focus - and nailing focus with f/1.9 is basically impossible without an electronic focuser.

Once I got auto-focus working on SGP it got rid of all my problems!
