Orion ED80T CF Triplet Apochromatic Refractor 80/480 F/6 OTA (SKU: 09534)

The Orion ED80T CF telescope is a remarkable optical tube designed for those seeking a universal solution that combines the best features of professional astrographs and telescopes dedicated to visual observations. Crafted with a lightweight carbon fiber body, this telescope offers outstanding performance and portability.

At the heart of this classic three-element apochromatic refractor lies an 80 mm aperture and an f/6 focal ratio. To achieve exceptional correction of chromatic aberration, the optical tube is equipped with a low dispersion (ED) lens made from FPL-53 glass. Furthermore, the lens surfaces have been meticulously coated with multiple layers, ensuring optimal contrast across the entire field of view.

The telescope features a Crayford-type focuser with a 2.5" diameter, enabling precise focus adjustments through its dual speed knobs and an impressive 11:1 ratio. With a maximum load capacity of 2.7 kg, the focuser maintains its linearity even when used with large, professional astrophotography cameras.

For convenient mounting options, the tube can be attached to a mount using the Vixen foot or screwed in place using a 1/4"-20 thread. The Orion ED80T CF model also comes equipped with an accessory foot in the dovetail standard, allowing for easy attachment of a finder.
