Autofocus

GoQat automatically moves the focuser and takes CCD images to generate a V-curve such as the one above. You can select the range over which you want to fit the slopes for the left and right hand parts of the curve. When the autofocus is calibrated, you can focus your telescope and CCD camera at the click of a button, as shown by the two images below.
