I finally decided to replace the stock focuser on my older, bino-friendly SW 120ED. The modified stock unit is "serviceable" but I've really gotten used to the quality mechanics and smooth operation of the AP and Feathertouch focusers. As luck would have it, a basically new ML 2.5" focuser with 3" draw tube appeared on AM and I found the Synta mating flange for the SW 120ED here on CN the very same day. So, I pulled the trigger.
This is my first ML focuser and boy, I'm impressed. The fit, finish, mechanics, and smoothness of operation are all first rate The mechanical stack ups between the stock focuser and the ML assembly were basically identical, making the ML system a direct drop in replacement. Once everything was on the work bench, replacement took all of five minutes...and I took my time.
