Product Description

Offered in 2x and 3x magnifications, these 1¼" Barlows perform identically. Simply choose either or both based on your eyepiece collection. Features include parfocalization, 1¼" filter threads, captive lock screws that won't fall out and full multicoatings.

Properly designed Barlows do wonderful things: They amplify power, slow the telescope's f/# (improving eyepiece sharpness), and give designers the opportunity to compensate for eyepiece aberrations.

TeleVue Barlows use multi-coated high index glasses for optimum aberration correction, exceptional contrast with virtually no light loss. Observed performance is aberration free, even when tested with f/4 scopes. They even improve our competitor's eyepieces and telescopes!

TeleVue Quality

Compromise image quality in any part of the optical chain and you've compromised every part! TeleVue product design and execution deliver consummate satisfaction. Every TeleVue Barlow must pass the same rigorous f/4, full field testing as all our eyepieces. All TeleVue Barlows now use brass clamp rings for secure, non marring holding of eyepieces and accessories.

Note: The Big Barlow is not recommended for use with 2" diagonals because it's length prevents it from being parfocal. With some telescopes, focus might not be reached, particularly when the interface lens is also used with it. A far better approach with no potential problems in any scope or with any eyepieces is to use the 2" 2x Powermate (PMT-2200). See the Powermates page for a discussion of Powermates vs. Barlows.

Televue 3x Barlow

Delivery from All Star in Edmonton AB to Burlington ON took a bit of time (July 22 to Aug 1) but not an unreasonable amount. Shipped via Canada Post. Quality of product is excellent as expected from Televue. Condition upon arrival was pristine , no evidence of damage to packaging or product. I’ll definitely be buying again.

Good for planets, very long barrel

I have enjoyed the view of Saturn using this Barlow. I can push it up to the optical limits of my modest 102mm refractor.

It's worth knowing that you can't use this Barlow with some combinations of equipment, because its barrel is so long. It is too long to insert into the eyepiece holder of small some telescopes or some diagonal mirrors.
