More Info

In keeping with our tradition of offering top-notch astronomy gear at great prices, Orion is proud to offer our 2" diameter, 2x Barlow Lens at a very affordable price. Like other 2x Barlow lenses, this big 2" model provides a 2-time power-boost to any 2" eyepiece so you can enjoy double the magnification of any 2" ocular. Just insert this Barlow into a telescope's 2" focuser and then insert any 2" eyepiece into the Barlow to double the power of the eyepiece.

This big Barlow has a huge 2"-diameter that's optimized to work with virtually all 2" telescope eyepieces. The 2" 2x Barlow is the perfect complement to 2" eyepieces such as the Orion DeepView and Q70 lines; and it works well with other brands of 2" eyepieces too. An included 1.25" adapter ensures all your 1.25" eyepieces will work with the 2" 2x Barlow Lens as well.

While 2" eyepiece users are often trying to stretch the limits of their telescopes to obtain wider, low power fields of view, there are many times when more power is needed to tease out detail from a small deep sky object or planet. Orion's 2" 2x Barlow Lens features multi-coated lenses for high contrast and glare reduction. It's even threaded for use with big 2" filters to further enhance your astronomical adventures.

Coatings

Coatings

Lenses are coated with an antireflective material to ensure that as little light as possible is reflected away, so more gets to your eye. Good lenses are at least "fully coated," with a single layer of magnesium fluoride applied to each air-to-glass lens surface. Multiple layers of coatings are even more effective; the term "multi-coated" means one or more lens surfaces have multiple coatings. "Fully multi-coated" is even better, meaning that all lens surfaces are multiple-layer coated. Mirror star diagonals are coated with a reflective material similar to telescope mirrors in order to reflect the light into the eyepiece. Standard aluminum coatings reflect between 88%-92%, and enhanced aluminum reflects 97%. Dielectric coatings use a different process to deposit a coating that reflects 99% of the light. In addition to the higher reflectivity, Dielectric coatings are much more durable than aluminum coatings, so they last longer and can be cleaned with less risk of damage.

Compression ring

Compression ring

Instead of a single thumb screw locking the eyepiece in place, a brass ring compressed by a thumb screw secures the eyepiece. This spreads clamping force over a larger area of the eyepiece's barrel, which provides a better connection. The compression ring also prevents the tip of the thumb screw from producing unsightly scratches and divots on the eyepiece barrel.
