Product Description

TeleVue 2" Big Barlow 

The Tele Vue Big Barlow 2" Barlow lens is a great way to expend your eyepiece collection by effectively doubling their magnification.  1.25" adapter is included so you can use all of your TeleVue eyepieces and, better yet, the Big Barlow is parfocal to all Tele Vue eyepieces.    By doubling the magnification of each eyepiece, your telescope's f ratio is also effectively made longer and by 'slowing down' the telescope, eyepiece sharpness is increased.    The Big Barlow's excellent optical quality  and fully multi-coated lenses will also further improve an eyepiece's performance by correcting small aberrations that naturally occur.    Eye relief can also retained which is great news for eyeglass wearers and others who enjoy a longer eye relief. 

Particularly well suited to use with a Newtonian telescope, At 4.5" long it is not recommended that you pair the Big Barlow with a standard 2" diagonal as the length prevents it from being parfocal. This is .  Brass compression rings keep your eyepieces snugly in place.  

5 Year Warranty!
