2 " "Four in One" adapter M68/2" /M68

This new four-in-one M68a / 2"/ M68a eyepiece projection adapter has four telescope-side threads, allowing the connection of 2" eyepieces or a 4-8X FFC fluorite Barlow lens as a projector for a variety of telescope brands, e.g.:

- all Vixen telescopes - with a 60mm thread on the draw tube

- all ZEISS equipment - with a 68mm thread

- all AstroPhysics refractors with a 2.7" thread

- Skywatcher/ Celestron refractors, all Synta telescopes - with a 56mm thread on the 2" visual back

- Skywatcher / Synta / Newtonian telescopes with a 60mm threaded connection

The 2" inner diameter socket has a bronze compression ring clamp with two large locking screws - meaning no wobbles. Combination with the M68a reverse ring makes possible a 2" eyepiece projection system for 35mm, medium format and for afocal projection. So even the heaviest professional digital and medium format cameras can be operated afocally - even in combination with 2" eyepieces.
