About this item

Versa 108 iOptron's first premium ED apochromatic refractor...

The Versa 108 ED doublet bears the same vision as our other popular products (such as the MiniTower and Cube) quality, value and innovation. Enhanced by the world's most advanced optical design and cutting-edge optical processing, this double air-spaced ED OTA offers a versatile platform that delivers exceptional performance for both visual observing and astrophotography.

With outstanding color correction and crisp imaging you'll be able to view beautiful images through your eyepiece, CCD camera, or DSLR camera. Versa 108 is an OTA anyone would be proud to own and show to their friends. Designed with superb mechanical engineering, precision machining and superior workmanship this OTA is a beautiful piece of art.

For users with serious astrophotography aspirations, the Versa 108 also includes a vital tool to enhance image quality a standard Field Flattener. This greatly improves the image sharpness at the edges of images.

Finally, to ensure the field performance of each and every OTA iOptron has retained the service of the world renowned astrophotographer Mr. PK Chen to examine and test every unit before it is released from the factory.
