Hello, I currently have my setup tripod mounted and I have to set up most nights I image. I find that the AO calibration often fails and I have to slew so that my guide camera is in an open cluster. Are there any tips on calibration and is there a way to dark subtract during calibration, not just actual guiding? Also, I will often come back after some time and the guide star is lost for seemingly no reason as I wasn't there to witness what happened. Is there a way to reaquire a lost guide star by prompting the image to stop, astrometrically reposition the scope and start guiding again? I also have the issue that, while the drive and AO calibrate successfully, the AO unit will max out and give the error that guider relays would not respond even though I am guiding using the telescope selection. Should I use an ST-4 cable for more reliable guiding or is this some other issue? Thank you!
