The stars aside, this is a wonderful, wonderful effort. I love what you're doing!

Richard, you could temporarily substitute the GSO secondary with the original smaller one, you will lose some illumination at the edge of the field but it will at least allow you to confirm if there's any issues caused by the GSO secondary or if the fault lies elsewhere without spending extra cash.

Ha... that might be it then.

A wonderful result!
