Telescope Eyepiece Adapter, 1.25” Focuser Adapter M42×0.75

Unbelievable quality and fit for the price. Threads on securely and holds eyepieces with confidence. The focal plane can be adjusted by threading the body in or out and the locking ring firmly sets the adjustment.

Excellent build quality. When I buy anything SVBONY makes, I know I will get a quality product.

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...

Building a Hadley 114 with a 3D printed M42 mount. Threaded on with no fit issues at all. Feels solid and was easy to test. An affordable well made option.

This helped a lot. Had my reservations originally but when I installed it worked just a sore petter you just couldn't beat it.

This fits my Meade 102 mm refractor telescope perfectly. This is the part that can unscrew, fall off, and get lost if you don't use a bag or disassemble your. telescope when you throw it in the car for dark sky viewing trips. I know, I know. Great find for hectic people like me.

Bought, along with a T2 male to male adapter ring, to replace the stock eyepiece holder on a Svbony 1.25" all metal refractor focuser. The three thumb screws allow centering of an eyepiece or other device and the threaded two piece design allows very fine micro focusing adjustment. Threads on the two pieces could be a bit more precision.

This product is excellent to have .The problem do not buy less expensive telescope or expensive telescope that is not with standard tescope parts or professional telescope .

Great quality of materials especially for the price.

if you have a svbony camera and you want to use an eyepiece (1.25") then you need this adapter, fix perfectly and it's a really good quality

Focuser does the job, solid focuser, would reccomend!
