have the adjust option ticked and it fills the screen, i use it all the time.
re focus with saturn, well i am not on speaking turns with saturn at the moment. went to bed early, got up at 11pm to have a go at saturn. conditions were warm and still. mirror was the same as ambient. scope star tested beautifully.
i spent 10 minutes trying to find saturn at 1000x and then 45 minutes trying to get a focus. the planet and rings were still, but whether because of high cloud or something else, i could not get the casinni division to come up.
gave up in disgust!!
another method, try a bright star like procyon, crank up the gain and brightness and gamma and see if you can get the star with diffraction pattern focussed, and then swing back to saturn.
this for me is more accurate than estimating a hartmann mask focus
qfocus has a focus section, but without electronic adjustment at the moment, it is too hard
