APQ helical focuser alternative

Greetings Zeiss friends -

Recently I bought a feathertouch focuser to use as an auxilliary focuser in my 10" mak/cass. I was so pleased with the operation of this unit that I revisited an old pet peeve of mine - the helical focuser on my APQ 130. I have been talking with Werner at Starlight about making an adapter to mount their 2" focuser with 2.5" drawtube on the APQ. With this arrangement there should be enough back focus for any configuration (including Coronado's BF30 blocking filter and Baader Mark V binoviewer).

If all works out I might arrange to make a few of these. If you have had a stormy love affair with the Zeiss helical arrangement and have any interest in this project - feel free to drop me a line.

cheers -

Alan Friedman
