## Description

desertcart.com : SVBONY Telescope Accessories Focuser Adapter 1.25 inches M42X0.75 Reflector Telescope Eyepiece Adapter : Electronics

Review: Must have to use 1.25" telescope eyepieces with microscope heads (just add T2 30 or 23.2mm adapters) - well made.... use these with a T2 to 30mm OD tube adapter to be able to use 1.25" eyepieces with microscopy heads or such heads converted to telescope use. Add a teeny tiny coating of nyogel 767a silicone lube to the brass screw threads and thank me later -- gives it that Zeiss-smooth rotation feel and eliminates vibration-induced falling out of same. It could save your eyepiece from falling out.
Review: Definite advantages to cheap rack and pinion focusers. - Mechanically beautiful, good value. For the scope builder. The knurled ring is threaded. Will try enhance with a little pipe tape on the threads. Simplicity for those who are discovering their deep sky objects visually. The thee point brass ring provides smooth control of focus. My reflector has a flat area for mounting, but should be adaptable to a round tube. Love the brass screws. Low profile focuser puts the eyepiece close as possible to the diagonal on a reflector telescope. Commended to the scope building community. Update here for the scope builder: I switched to red lithium grease on the threads instead of pipe tape. Slack in threads is normal with zero taper. Slack can then be taken out with knurled ring tension. I put some black tape on outside of ring. Operation is smooth and no mechanical play. Ready for the stars...
