Hi Adam,
Here is more to it. Today I have made the pulley I will use to connect the lens to the motor focuser. I chosen the same 180 teeth that I have made to the Canon 300 mm lens.

Here it is:

Now it's complete and ready for some test photos, but first I shall test my Canon lens more. Take it out to some dark place relative my home in the city.

ps.
Your Canon 500 mm f/4 lens must be very exiting to use for astrophotography.
