I have reported evidence the newest update DID NOT adequately address the horizontal streaking stars on S30Pro that happen way too often. Also, the decision made in December to try to support now three different telescopes in one app/firmware has left ZWO software team too confused. The dithering of the S50, which had been increased last April/May is now back to very little dithering. Results are unsurprising: bands of walking noise have returned.
A: please go back to what worked with the S50 dither.
B: let a lot of us know if we need to ask for exchanges, as the laxity/freeplay/backlash in the S30Pro is apparently NOT something you can adequately address with software/firmware gimmicks.
