I can't find the astromechanics focuser driver was created by ezwheels

I just received my Astromechanics Canon lens focuser and I can not find the driver to set it up in the profile editor.

Is it under a different name?

The closest thing I found was in the AO list of drivers under Astromechanics FOC. This does not connect.

I unplugged one of the USB A cables ends from the back of the iMac and replugged it in and it connected right away. Focus seems to work while testing it on my bench with my 200mm f2.8. F-stops are set in increments from 1-22. I do not know if this corresponds to custom f ratio set points or if it is approximating the closest Canon f-stop.

Looks like this driver needs to be moved to the focuser driver folder. Should be fun to test it out under the stars hopefully soon

There was a typo in the XML file for the astromech focuser driver which I just fixed. So wait for next nightly and you'll see it under "Focusers". Thanks for the report!

Great!

Any input on the f-stop settings? Does the driver set custom f-stop ratios? i.e. does 1 on the INDI driver control panel equal f1? Or does it move the shutter to f2.8 as that is the native fastest f-stop on this particular lens. I am pretty sure there is a f22 in the native Canon design so that one would match up. The way the lens aperture ring moves when this setting is changed is that it first opens all the way wide open then closes to the INDI driver selected setting so it is difficult to see the difference when just looking at the mechanism when making a change between the INDI setting of 1 and 2.

Hi!

It moves the shutter to the fastest f-stop on your lens.

Copied from the documentation of the driver:
* Apperture : setting index of lens apperture (0: apperture fully opened e.g. f/2.8, 22: apperture closed e.g. f/22)

Best regards,
Chris.
