I have a spare 4" rack and pinion focuser from an FLT-110 APO selling for $450 negotiable. The internal thread at the front end is for a 115mm OD tube with 1mm pitch. White finish with gold and black anodize. The focuser rotates, with finely machined set screw lock and knobs; includes the 4" to 2" step down adaptor.

thanks,
Arief

Reduced to $350 only. The 4" focuser is ideal for 4.5" or bigger refractors (I was thinking of using this on a 5" f/15 or 6" f/12 D&G refractor).
