Boy did you luck out! You must have had a great polar alignment and really good PEC!


The track centroid function is a 'software' track in that the window being displayed moves in the frame in response to the shift of the star in the image. The purpose is to make sure that image shifts during focus do not throw the star out of the box. There are no adjustments sent to the LX200. Hence my comment about your luck.

I am glad it worked out for you but this is not using the 416 to guide.
