I also purchased a 2" extension tube. Looks like the price on the focuser went up $16 since my purchase. Both combo focusers are silky smooth. I decided to order two finder mounts. The RACI on the left, and the red dot finder on the right. Cant think of anything eles I want to add to this great refractor which I got used for $250. Left click the images.

Congrats RD! This is a nice focuser. I have it on my short and chubby brother of yours. It handles 2" filter wheel with hefty Baader diagonal and EP no problem.

Enjoy the new focuser.

My old focuser looks kinda pitiful laying on my observation chair. It did work for me, but nothing like the very smooth dual upgrade.

I'm looking at a GSO for my ST120. It made a huge difference when I put one on my ST80. The stock R&P does look pretty sad next to a Crayford.

ST80 stock focuser is pretty bad, so replacing it with GSO is a big improvement. But I like Synta one speed 2" focuser they put on many Celestron, Orion and SW models including 150ST, 120ST and the yard canon. After re-greasing and adjusting tension it is not bad. I kept the stock focuser when I had 120ST and the only reason I have replaced the stock focuser on 150ST because I needed longer focuser travel for my filter wheel.

Just got back in from a first try with my new focuser. First shot was the Moon at 240 magnification with my zoom eyepiece and barlow. There is no doubt that I can get quicker and better focus with the dual adjustments. The telescope now has a much more professional feel to it. A truly great investment.

I am seriously looking at this one for my Vixen.
