Recently, thanks to YouTube tutorial, I adjusted the AVX mount gears to reduce the large amount of RA backlash. I also made a few PHD2 settings adjustments. I had been using the recommended 1.5 to 3s guide camera exposures. I reduced that to 1.0s and reduced the RA aggressiveness to an experimental 50%. These changes have resulted in an improvement in guiding as evidenced by rounder stars and a less noisy guiding graph. The images below were acquired over two days of imaging.
