Is it possible to do autoguiding with the NexStar while in regular AltAz mode? My reason for wanting to do this is not to achieve long exposure but just to help keep my object centered better throughout a session. I've fine tuned my backlash and have added extra reference points to my StarSense model but I'll still get the object drifting around the FOV. It doesn't actually drift out of view, but drifts up and down gradually. This is a problem because I'm using a small 1/3" CMOS chip and I wind up having to do a lot of cropping on an already small image to remove stacking artifacts. My thinking is if I could just keep the object centered better I would at least solve that problem. I'm still expecting to be limited to 10-20 second exposures, that's OK.
I realize nothing about the 6SE is well-suited for DSO work, but it's what I have and I want to try to work with it rather than throw money at the problem (different mount/OTA/camera/wedge). I'm also not interested in a wedge because I don't want to deal with polar alignment. I like the ease of just plopping the AltAz down and kicking off StarSense and I'm done in 2 minutes.
Let me know if anyone has done this or at least knows if the autoguide port is disabled in AltAz mode. If this is doable can I just use the standard PHD2 software, or does that assume a GEM mount?
