Gonna finally let these go as I've been hanging on to them for a long time waiting for the next reflector project and it hasn't happened yet.

Jim's Mobile Next Generation Focusers are ALL world class and when it comes to the Crayford design, they have it all as finely-honed as they can come. These are ultra smooth, non-shifting, no drooping, and gorgeous-looking focusers that any high-end reflector is deserving of.

Barrel size: 1.25-inch
Materials: milled aluminum, brass, teflon
Weight: 11 ounces
Total focus draw: 1.54-inches
Bolt pattern: (4) bolts equidistant square pattern 2.61-inches apart
Curved to fit: any tube with outer diameter from 6.0-inches to 18.5-inches
Payload: up to 1.6 pounds (heaviest tested) without slippage

Remember, Crayfords are NOT rack-and-pinions; these are focusers that use bearings to transfer friction to the draw tube for precise operation.

The one on the left is in very excellent condition for its age and buttery smooth operation. Locks firm when required. Comes with original leveling screws. You need your own mounting hardware. $85.00

The one on the right has a replacement set screw for the focuser (teflon) and has a variable iris diaphragm mounted on the bottom of the draw tube for imaging purposes. It can be left alone if not needed as no ocular barrel will come close to clearing and hitting it. The focuser is in excellent condition and is also smooth in operation. Shutter operation is perfect. Does not come with leveling screws or mounting hardware. $77.00

The last (2) photos shows the right model with the iris fully shut and the last photo shows it fully open.

Prices don't include shipping. Will ship to anyone on Earth.
