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.

But the real surprise was I did not have to do any tweaking what so ever of the SW's tube adapter or the ML system.   Both the laser and Cheshire reflection dots were perfectly lined up!

 

Now just how often does that happen?!  The "sauce for this goose" is that with the 2.5" ID draw tube, I got an extra bump in the fully Illuminated field at the focal plane with the viewers of maybe 4-5 mm.  Nice.

Moonlite is awesome! They collimate them at the factory.

 

I've had many of them and I like them very much.

Very good! me too, all FeatherTouch and MoonLite. I retrofitted to my old classic TeleVue Genesis and is magnificent. For that scope, the MoonLite-specific custom adapter was perfect interface. That changed the backfocus and range a bit, but entirely copacetic.    Tom

I had a 2.5" ML on my Istar 5" f/12.  The only Crayford I would consider as original equipment on any scope and the only one on a par with premium R&P's.  Outstanding quality, mechanics and workmanship.

Cant go wrong with a moonlite.  FT is a bit better but a lot more expensive(some cases double). Spend your dollars accordingly.  There is room for both brands as they fill their niche well.

Used a 2.5" ML one on my Orion ED100. Liked it even a little better than my FT 2.5". Fine focus was so smooth.

I had a moonlite 2,5" focuser at my NoName ED 102/714 refractor and it was great. They had the right adapter for the focuser ,so the change was very easy. I just screw it on and it works very fine. The colour matched very good with my scope.
