Takahashi wasn't messing around when they designed and built this state-of-the-art 2" Diagonal! The elliptical mirror itself is made of Pyrex and is guaranteed to have an overall peak-to-valley error of less than 1/10th wave. Enhanced aluminum overcoats the mirror and produces a beautifully sharp, bright image. The mirror is mounted in its holder with assistance from a beam collimator to assure perfect alignment.
The 90º diagonal housing is made from a solid block of aluminum and black anodized. The 2" chrome barrel has a safety indent to keep it from falling out of the telescope should you loosen the thumbscrew to rotate the diagonal, etc. The inside of the barrel is matte black to keep reflections at bay and it is threaded to accept 2" filters. The 2" black-anodized barrel has a safety stop built in to make sure the barrels of your eyepieces and accessories do not slide down too far and hit the mirror.
The Takahashi 2" Diagonal comes with a 2" to 1.25" adapter so that you can use 1.25" eyepieces and accessories as well as 2" models. The adapter has an included metal dust cap, and another dust cap is provided to cover the barrel that inserts into the telescope.
To use the Takahashi 1/10th Wave Diagonal on the FSQ-106EDX4, you will need the #70S Eyepiece Holder (TKT37110, old product number TOA0401), as well as two pieces that came with the FSQ.
