Here I am. The Micros are excellent, I had one on a Tak refractor focuser, and they are also available for the SCT models. The only comment I have is they only provide fine focus, and are not the magic bullet to fix mirror flop, or slop in a R&P focuser. One of my Taks had a little shift in the R&P, and while the 10:1 was nice, the shift was still there.
They can be sourced from the above Starizona site, or direct from Starlight Instruments

I did have a few newtonion type focusers etc, but don't have any Micros. If you need help sourcing one, contact me off group.
