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. Compromise image quality in any part of the optical chain and you've compromised every part!

All TeleVue Barlows now use brass clamp rings for secure, non marring holding of eyepieces and accessories. TeleVue
