  • Doubles magnification with 2x optical power
  • Reduces aberrations using two high-index glass elements
  • Accepts 1.5" filters via integrated threads
  • Secures eyepieces with captive lock screws
  • Maximises light transmission through full multi-coatings

Telescope Barlow Lens 2x

The Tele Vue 1.25" 2x Barlow Lens doubles the magnification of compatible eyepieces for astronomy enthusiasts. It uses two elements of high-index glass to reduce aberrations even in fast optical systems. Full multi-coatings maximise light transmission for bright, high-contrast views of celestial objects.

Parfocal Design Filter Threads

This lens replaces the need for multiple high-power eyepieces by amplifying existing focal lengths. The parfocal design maintains focus when the Barlow is inserted or removed during observation. Integrated 1.5" filter threads allow direct attachment of standard astronomy filters without additional adapters.

Secure Locking Safety Groove

Captive lock screws and an internal safety groove prevent accidental separation from the telescope or eyepiece during use. The optical design slows the telescope focal ratio to improve edge sharpness across the field. Blackened lens edges and anti-reflection threading suppress internal scatter for darker sky backgrounds.

Questions about this item

Does the 1.25" barrel fit standard telescope focusers?

The 1.25" barrel slides into any standard 1.25" focuser or diagonal and is held by captive thumbscrews with an internal safety groove.

How do I attach it without the lens rotating or falling out?

Insert the Barlow into the focuser, tighten the captive thumbscrews against the safety groove, then thread your eyepiece into the top and secure its own thumbscrews.

Will the 1.5" filter threads accept my existing astronomy filters?

Yes, the 1.5" filter threads on the Barlow barrel accept standard 1.5" threaded filters for visual or imaging use.
