Celestron Ultima 2x Barlow – A Classic Compact APO Barlow Lens
The Celestron Ultima 2x Barlow is a compact air-spaced, 3-element apochromatic design with a 27mm clear aperture. All lenses have full multicoatings and it’s guaranteed to render exquisite quality images.
The big benefit of the Celestron Ultima 2x Barlow is its compact height. At only 75mm tall, the 1.25″ barrel will fit easily into star diagonals or other accessories where conventional, longer style Barlows won’t.
The key to its performance advantage is the triplet lens design. Compact Barlow lenses that only employ a doublet lens cannot sufficiently suppress chromatic aberration, spherical aberration and coma. The air spaced triplet design of the Ultima Barlow minimizes these optical flaws resulting in a far superior image quality – you get sharper images with 2x the magnification.
We have a small quantity of these Barlows to clear at this price. If you’ve been looking for a high quality affordable Japanese made Barlow here’s your chance.
