Hello Robert, after yesterday phone call i add a new dome control in Voyager called ASCOM Dome HitecRoof with some changes to have more log info at monitor and in a log file. Also i slowed down the polling time of status. Please do some test with this version and send me back log from ASCOM and Voyager. Take two set of log: one normal and one activating the flag in voyager setup, tab voyager, box Logging, flag “ASCOM Extended info” activated. After test remove the flag.
