Olivon 2" Mirror Diagonal  2寸OL平面棱镜
Some of the world's most expensive mirrors use Dielectric coating, which can distort the surface and cause aberrations in the reflected light. Though Dielectric coats cost nearly double that of Aluminum-coats, at Olivon Scopes & Optics, we use Aluminum-coats for all of our mirrors. The reasoning behind that is to provide the highest quality materials to produce the mirror, with super precise machines to make it super ultra-flat, and provide the best viewing enjoyment with a coat that doesn't distort your mirror over time.If that reasoning makes sense with you, then the Clarion 2", 90 degree Ultra-Flat Mirror is what we would like to introduce to you. The mirror itself is manufactured by Synta, a super ultra-flat mirror, not found in some other so-called 'quality' diagonals in the market. With complementing 2" eyepieces, the Clarion is capable of allowing a wider field of view. The Clarion includes an adaptor to attach 1.25" eyepieces, and has another adaptor for use with refractor telescopes as well.

$145
      Olivon 2" 90-Degree Erecting Prism Diagonal  2寸OL棱镜天顶
The Superior 2" 90-Degree Multicoated Erecting Prism diagonal takes advantage of a wider field of view through the use with 2" eyepieces. This gives astronomers a great view of the illustrious stars and the magnificent heavens above. The body of the cool sleek prism is made of finely machined aluminum, which provides a lifetime of durability and steady viewing. The Superior includes an adaptor to attach 1.25" eyepieces, and has another adaptor for use with refractor telescopes as well.

$199
