Pro's: cheaper (by about £50?) than the MEF-3, easy to fit and the 12:1 ratio works very well.

Con's: heavy, if you are installing it on an FOA-60 or FS-60/Q you will probably need some form of counter balance, that's the option I'm looking into anyway. On a larger scope say FS-78 onewards I don't think the weight will be too much of an issue. The coarse motion is quite stiff compared to the stock Takahashi focuser (I've not tried a MEF-3 retro fit so I can't comment on that) but if the stock focuser is quite loose as it is my FS-60Q then it has helped firm that up. All in all though I'm happy with the purchase.

This 12:1 fine focuser is a great replacement for your standard Takahashi focus knob. I considered the Takahashi MEF3 fine focus knob but I was put off by the much higher price. The only thing I didn't like was the mounting bar. It is too flimsy for this application...it is not ridged enough. I would up making a heavier mounting bar out of mild steel and this More Blue fine focus knob is very smooth and precise. My FOA-60Q is complete now.
