Completely brand new user! So I am installing Voyager on a Win7 machine where the only ASCOM device will be the focuser. Everything else will be SkyX. The focuser has been working perfectly fine with ASCOM 6.4 SP1. Will it still be necessary to update that? I know ASCOM is supposed to be backwards compatible but always concerned when making a change to something that’s working 
Thanks
Dave
Hi Dave,
you can try to use it as is because ASCOM 6.5 is needed only for flat device and some advanced features for camera.
Let me know about.
All the best
Leonardo
Great! Thanks.
