Hi David
Just on a couple of points that you have raised:
Ra Agressiveness: Going to the max of 120 would appear to be a bit high as this may give too much correction overshoot. I usually find 70% is about right.
Dark Frames: I do find that when a dark frame is employed that the screen has a dim white "wavy" wash against the black background, however the
stars seem better defined. You can fiddle around with the Screen Gamma
slider to improve the visual look of the display but I have found that this does not affect tracking so I just leave it on default.
Calibration: this depends on your scope focal length but I just set it so that it gives noticeable steps across the screen (eg about 1mm) for each
calibration step. I don't know whether and/or how the calibration setting affects guiding but someone may like to comment on this.
Cheers Peter
