This is brand new - the base profile is too narrow for the 3" hole in my Dob, so I must stay with JMI products.

From Moonlight with the 10" dia tube adapter : $270
$205 shipped via US Priority Mail.



1.45" low profile, Zero backlash, No image shift crayford design.
2" travel, 3.3" long draw tube.
Vertical lifting capacity is 5 lbs. and is user adjustable for even greater capacity if needed.
Super smooth focus rate is .58" per revolution on standard side.
Inline slow motion has an 8.2 to 1 ratio.
Flat base dimensions are L=3.5" W=2.9" H=1.45"
Weight: 15.8 ounces.
Tip/tilt focuser alignment screws located in each corner of the base.
Sealed precision stainless steel bearings with lithium grease.
Base is highly polished, red anodized 6061 aluminum.
Draw tube, and adapter is highly polished, black anodized 6061 aluminum. (The flat on the draw tube is hand polished perfectly smooth which is why our focusers are so smooth-- No machine marks are left on the draw tubes' machined flat surface. This allows very small focus adjustments to be made without any sticky or notchy feel to the user.)
Knobs are 1" knurled 2024 polished aluminum.
All hardware is stainless steel.
Thumb screws are black nylon.
