Mk III model features 80mm f/6 air-spaced triplet optics with Hoya FCD100 ED glass element and an impressive poly-strehl value of 0.979. 

Other features include 2.5" dual speed Hex focuser and carbon fibre tube.

The Explore Scientific ED Apo 80mm f/6 Carbon FCD-100 MK III represents a new step-up in optical quality for Explore Scientific. Explore's commitment to the needs of higher-end imagers have led them to develop this new version of their popular 80mm triplet Apo. Rather than the excellent FCD1 element, this design uses the even higher quality FCD100 glass - leading to a poly-strehl value of 0.979: an absolutely first class measurement for a telescope of its value.

The Explore Scientific ED APO 80mm f/6 Carbon FCD-100 MK III comes complete with the 2.5" Hexafoc Hexfocus system, which offers an unobstructed internal view for larger imaging chips. The Hexafoc system is designed to support the focuser's draw-tube equally, no matter which orientation the system finds itself in.  This focuser naturally comes with a dual speed 10:1 reducer for fine focus adjustment.

This telescope is also supplied in the Carbon Fibre finish tube, which alongside being extremely attractive, saves weight when compared with conventional Aluminium tube models.  The system also has a retractable dew-shield and two extension tubes, in order to keep tube length down to a minimum for shipping and transportation.  The telescope is also supplied in a heavy duty flight-case, with specially cut foam inserts, in order to offer the greatest practical protection possible.

Please note, no finder is included in this package, though the finder footer will take both the Explore Scientific 8x50 finders and the Meade 50mm finderscopes.
