Triple the magnifying power of your telescope eyepieces with this S-T11 3x Barlow Lens for 1.25" Telescope Eyepiece from Neewer. It's simple to use—drop the Barlow into your focuser and slide the eyepiece into the Barlow, tightening it in place with the knurled fixing screw. The Barlow accepts all standard 1.25" eyepieces. It also has a male M42x0.75 thread for attaching to camera T/T2 adapters. Light transmission is optimized by multiple full antireflective glass coatings and an antireflective interior finish for a bright, clear view. The Barlow is made of metal with a knurled rubber grip ring. Thanks to an internal brass compression ring, the fixing screw won't mar or damage your eyepiece.
