When I built my 6" f12 frac I decided on 38mm as my Illuminated Field size.
Works well and was just a number I chose not wanting to go the max of 42.
There is very little info out there on the subject.
Great views with low power eyepieces.
Used the same baffle method that gave me what is in the photo. I still haven't got around to installing the first baffle, mostly as it is 5mm thick....gonna have to wait for a router to cut it. In the meantime I use flocking to my first baffle and can't complain at all.
