Hi Colin,
As I reported on the ASCOM help forum, your beta driver .242 is working well with my LX200 Classic using the latest version update for Platform 6.5 and Device Hub. (It also works well using POTH and Platform 6.5)
I have had no problems using APT. There is one glitch in SGP that may or may not be driver related. The plate solve and center routine can't center within the set pixel error of 50. APT centers within that error with no problem. SGP does well on the initial solve and slew but can't get closer than about 100 before it runs out of tries and fails. Would adjusting the driver guide rate have any effect there?
Other than that, everything seems very stable and working great. Great job!
Jeff
