I downloaded and installed the latest update for MaxIm DL, version 6.30. With setup using the AO on Sensor 2 and a self-guiding filter wheel, I get a window for calibrating both the AO and the ordinary guider. In both, I get very strange calibration lines, which look like a representation of a meteor radiant to the calibration star. For what I mean, see the attached graphic. Suspecting a hot pixel, I used a master dark for calibration of the guider. No difference. If I turn off the AO guider and use the normal guider calibration, I get the familiar "L" shape. Looks like something is wrong.
