TRAPPIST - last : I noticed acquire star is looking for star sometimes very far (2 deg), then finds a lot of candidate for focus (mag 11-12) about 1000 stars and then it looks to me this is slowing down FocusMax. Is there a way to say to FocusMax to only look to a smaller field ?

Berg - The next little bit of code establishes the FOV window for selecting a focus star. It's set for 5x5 degrees by having PL.ArcsecPerPixelHoriz = 600 and PL.ArcsecPerPixelVert = 600. If you change 600 in both places to 120, you'd search a 1x1 degree field. If you change 600 to 60 it would search a half-by-half degree field. Set your own threshold.
