A primitive guider for Agile that works from science images. The guider is primitive because the guide loop is in TUI instead of in the hub where it belongs. ... Specify a guide star (set Star Pos and Centroid Rad ) one of two ways: . ... Then for every Agile image the guider will try to centroid a star at Star Pos and offset the telescope (using boresight offsets) to center the star at that position. ... The guider never modifies any entry field (Star Pos and Centroid Rad) unless Find is checked. ...
