Will place the Tak 180 Epsilon on the AP1200GTO mount.

I have found a site where someone uses a Robofocuser motor and used different size pulley gears to improve the focusing.

Currently, I'm building a 12.5inch f/4 and will try it with a Keller focal reducer so get it near f/2.8. I had used this focal reducer on an AstroTeck 8inch f/4 and it worked well. At present it is the focuser that is holding me up. I ordered and paid for a FT3515 in Mid January and Wayne tells me that my order is in the "pipe line" and I have to wait my turn.
