Vixen 2x Barlow Lens 31.7mm – Double Your Telescope Magnification for Detailed Moon & Planet Viewing (ES3907)

Double Your Eyepiece Magnification — With a Built-In T-Ring for Camera Imaging

A Barlow lens is a simple accessory that inserts between your focuser and eyepiece, effectively doubling the magnification of any 1.25" eyepiece you own. A 20mm eyepiece at 50× becomes 100× — without buying a new eyepiece. The 3-element optical design is well-corrected for aberrations, keeping images sharp even at higher magnifications.

What makes this Barlow stand out is the built-in T-thread on the eyepiece end. Attach a compatible T-mount adapter (sold separately) and it doubles as a camera adapter for prime-focus astrophotography — a practical two-in-one accessory.

Note: When used with a star diagonal, effective magnification increases to approximately 2.6×.
