VERSION 1.0.0 - 12/02/01 - Initial Release

Initial release - A limitation in the Starlight Xpress USB driver and hardware for the camera interface only allows the vertical position of the star in the focus window to be moved in 30 line steps.  This means that depending on where the star happens to fall in the main image, a 1 pixel change in the selected position could cause a jump of 30 lines in the position of the star in the focus window.  Likewise, the star may be located in the main image such that a large movement of the selected position doesn't cause the star to move at all.  For this reason, it may be necessary to use a larger ROI and/or reposition the telescope to better align the selected focus star.
