Recently set up my ASI Air Pro with AVX and WO Z73; ASI 533 Camera and ASI 120 MM Guide on WO 50 mm guide scope. Set up was amazingly easy and everything seemed to be going smoothly except for guiding! (Same issues as all of the previous posts. Has ZWO come up with the fix yet (I see that it has been since Oct 2020)--Strange that it seemed to work the other night and guided well; however last night, it was not able to track and RA was off the charts. Any advice? Thank you---I am still somewhat of a beginner and would love to get my first DSO sequence!
