I recently built up a Raspberry Pi 4 with Stellarmate for use with my minimalist AZ-GTi and a Canon T7 setup. In general the whole setup works about as advertised with the exception that the auto-focus feature in Ekos doesn't do anything with the focus on my Canon lens.

 

Does anyone have experience with this sort of minimal setup? Is this a problem with my specific lens or a problem overall with Canon DSLRs, or all DSLRs in general? 

 

When using the camera by hand with the lens in AF mode the camera will auto-focus as expected for daytime photography, and I do hear the motor in the lens during focus, but with Ekos I never hear the motor.

 

Any info greatly appreciated.

 

Thanks

Could be that the EKOS Focus Routine is for dedicated ASCOM-driven telescope focusers, not Canon lenses ?

With some guidance and clues from Jesem I am able to run live video and focus remotely by hand. StellarMate/Ekos has a mode where I can run the video 10x, so similar to being in zoom mode on the camera itself, and then I can hand focus from inside the house so this is a big step forward.

 

With the Ekos Auto-Focus feature I seem to crash the Canon driver and have to do a restart so I won't be using that for awhile yet.
