Hello Eric,
i hope this thread can help you:
Voyager doesn’t use PHD2 setting for dithering but decide in autonomy so leave 1.0 on default scale. Pixels in Voyager are related to guide camera if you are guiding, if not are related to main camera. In the second case you have nothing to calculate in the first you must do this calculus:
Scale imaging/guiding = 1.1 / 0.84 = 1.309523…
10 pixel in guide camera = 10 / 1.309523 = 7.63 pixel in Main camera
If you want to move main camera of 10 pixel :
10*1.309 = 13.09 pixel to put in dithering in Voyager
All the best
Leo
PS i never used scale field in PHD2 and i dont know if work from external program (probably yes) , if work you can just input scale calculated of 1.309 and leave 10 pixel in Voyager. Like i said never tried.
