Just seeing if anyone has converted their original focuser on a Tak refractor to the latest Feathertouch full focuser unit {not the micro assembly} and happy with the upgrade.
Thinking of changing one on a TSA-120, the focuser is good but for fine movements with heavy loads {even a 2 inch diagonal with a largish eyepiece} inward focus is not possible.
The feathertouch is rated for 15 pounds which is great but wonder if that is with the brake semi/fully engaged. Also the adapter/collar has three set screws that function as a camera adjuster, looks good but worried about how it self centres /collimation ?

I wouldn't. ..

With the Tak MEF dual speed add on to the stock focuser, my FSQ-106N will focus with a 2.5kg CCD camera hanging off the back easily, and at f/5 the critical focus zone is microns of movement.

Adjust the Teflon tensioner screws (the sealed grub screws on the top of the focuser between the lock knob) for better tension/feel.

It seems not many know how to adjust a Tak focuser. It is very simple actually. I have also now fixed 2 "broken" or gritty MEF units - again very easy. Last one, which was terrible, took me about 5 minutes...

We have converted ours. The standard Tak focuser is nice, but the feather touch is miles ahead in feeling.

Cheers:thumbsup:......found this article (http://www.astrodon.com/custom/_2e2a/content/files/Using%20an%20Astrodon%20MonsterMOAG %20with%20a%20Tak%20FSQ-106N.pdf) for adjusting the orginal Tak focuser and will give it a
go. I can't detect any movement {or flex} in the focuser it's just using the fine focus it wont rack in, even with applying tension with the locking knob, my 106 has the same problem as well .

I thought the TSA focuser was fine but as I was given a FT MPA for it by a very generous vendor, I fitted that and yes it was smoother but not by much.

Should that read: Even WITHOUT applying tension with the lock .......
