ZWO just released a TestFlight Beta v1.4.4 (build 17), firmware 5.57.
The iOS TestFlight "What to Test" says "fix the bug of RST mount" !
I just tried it and it is as smooth as silk now.
Currently, Pollux is towards the East, Capella is less than 1 hour East of my Meridian, Aldebaran is just a little bit West of the Meridian.
I started with no hand-controller (with ASIAIR, I have found in the past that I don't need the RST-135 hand controller, so I always leave it out). The mount started at the home position (West horizon).
I did a GOTO in ASIAIR (remember I don't use hand controller) to Pollux, and the mount executed a Meridian flip to go from the West horizon to East of the Meridian. This is already a good sign because the original bug (my UTC-8 was set to UTC+8) would have caused Pollux to be "below horizon" and the mount not move because of the horizon limit that I have set.
I next did a GOTO to Aldebaran (just West of Meridian) and the mount did another Meridian flip -- this means that the mount knows that Aldebaran and Pollux on different sides of the Meridian. Finally, I did a GOTO Capella, which is less than 1 hour East of the Meridian. The mount executed another Meridian flip to get there. This mean the Local Sidereal Time is probably spot on.
I will continue to keep an eye on the 1.4.4 beta releases, but right now, it looks like ZWO has squashed the UTC offset bug. If you are part of the Beta program, be sure that you download build 17 of the Beta (with the 5.57 firmware).
Thank you, developers at ZWO.
Clear skies,
Chen
