ASCOM Ioptron CEM25P

[festoon1]

Expected Behaviour

Controlling Ioptron CEM25P with Stellarium. Telescope connects in plug in and I can see the location of the telescope. I expect when I press Ctrl+1 the telescope slews to object

Actual Behaviour

Mount does not slew to object. Occasionally it does - but this happens a long time after pressing, but mostly nothing happens. Log file looks fine. It is connecting to telescope. I am not using StellariumScope - I thought I did not need it for this version. Controlling mount works fine with Cartes du ciel

System

• Stellarium version: 0.20.2
• Operating system: Win10

ASCOM saw an update to version 6.5 recently which seems to cause problems with Stellarium. Did you try Version 6.4?

Thanks. Did try 6.4 SP1 but still seeing same problem
