When used with the included T-2 adapter and a DSLR (with T-ring, such as the new Baader Protective DSLR T-rings), the projection ratio is approx 2.2X.\u003c\/div\u003e\n\u003cdiv style=\"box-sizing: inherit;

Only 2 elements of high index glass were required to reduce all aberrations to well below the airy disc in an f\/4 system. It has taken a good 15 years, but I think we’re finally laying to rest the popular myth of the “degrading Barlow.” In a 1997 Sky \u0026amp; Telescope review, Terrence Dickenson wrote “…Technology has erased the old objections. A modern Barlow will not degrade your telescope’s optics. Anyone telling you otherwise is using outdated information. Moreover, the highly regarded Nagler eyepieces and their clones have built-in Barlows – ample evidence that the lens is not some detrimental intruder.” Thanks Terry, I couldn’t agree more.\"\u003c\/em\u003e \u003cstrong\u003e— Al Nagler\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\u003cp\u003eProperly 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.\u003c\/p\u003e\n\u003cp\u003eTele Vue Barlows use multi-coated high index glasses for optimum aberration correction, exceptional contrast with virtually no light loss.
