Ascom command RightAscensionRate result in the wrong RA rate. #41

When I set the mount rate in arcsec/sec via method:

https://ascom-standards.org/Help/Platform/html/P_ASCOM_DeviceInterface_ITelescopeV3_RightAscensionRate.htm

Then the mount rate is much too high. I works for the simulator "Telescope simulator.NET"but not for GS Server. Maybe a factor 3600x wrong?

Han,

Are you using arcsec/sec to test this? I think it's seconds per sidereal second. The right ascension tracking rate offset from sidereal (seconds per sidereal second, default = 0.0)

han-k59 commented 1 year ago

Yes it is seconds per sidereal second.

The RA rate of "telescope simulator.NET" has changed a factor 15x since Peter introduced version ASCOM 6.6sp2 beta. I used to compare with ASCOM simulator 6.6SP1 but that was a mistake. So likely the fault is not in GS Server. I will check again next days and report back.

ok, just let me know and thanks for all the testing you've done!

Unfortunally RightascensionRate is still too fast. I estimate about 220x too fast. This could be a factor 15 multiplied instead of divided since 15x15=225.

The DeclinationRate method seems dead. It doesn't move the declination even if I set it at 3600"/hour.
