As the CCD chips in our DSLR cameras get larger it is ever more important to have an unobstructed light path to prevent vignetting. The manufacturers of high end scopes wisely put 2" eyepiece ports on them. Why then do we insist on putting a 1.5" bottleneck before your camera?

T-Rings have been around for decades, a legacy standard that is long outdated. They exist not because they are the best solution for imaging, but because they are the easiest solution for manufacturing. After all it's much easier to spin a standard thread on all adapters, regardless of telescope port size or camera brand. The T-Ring may be convenient but it is simply out of its league on a scope with a 2" eyepiece port.. especially with a camera that can take advantage of it.

Our True-299 UltraWide Adapter is a true 2" prime focus adapter that takes you directly from the bayonet mount to a 2" barrel with as few wasted photons as possible, adding as much as 10mm more clear aperture over legacy adapters! The largest clear aperture of any adapter on the market. And it costs little more than a quality T-Ring and 2" T-adapter. Fully baffled to reduce reflections and threaded for 2" eyepiece filters. Available with or without a safety undercut on the barrel. True-299 was the first the 2" UltraWide adapter and it's still best. Don't choke the photons out of your camera with an inferior adapter!
