I own a new camera and filter wheel above. I use Maxim version 6.21. I start up the camera in dual chip mode and set up "camera 2" as the guider. I have run the guiding chip integration time up to the 30 seconds and I still get a blank readout. No noise at all, just a black screen. I am puzzled as I can get an appropriate star field and noise readout on the "camera 1" imaging chip even at a few seconds. The filter wheel is set up with the first slot being open, slot 2 is L, slot 3 is R, slot 4 is G, slot 5 is B, slot 6 is Ha, slot 7 is S2 and slot 8 is O3. Even with the wrong filter set up, I should get noise from the guiding chip. I am lost and really need help. What have I failed to do to get the guiding chip to give me a read out. Thanks.
