GSO's 2" refractor diagonal features dielectric coatings with 99% reflectivity across the visible spectrum and a 1/12 wave BK7 mirror. The all metal diagonal body is CNC machined. The combined result is a superb diagonal offering excellent mechanical and optical quality at a great price. Dielectric coatings are more durable than regular or enhanced aluminum coatings, so you will enjoy years of excellent performance from this product. Diagonals with comparable quality and specifications often sell for $150 or more in today's astronomy market.
The 2" chrome barrel of this diagonal on the telescope end is threaded to accept standard 2" filters. A 1.25"-2" adapter is included so you can use this diagonal with 1.25" or 2" eyepieces. The 1.25" and 2" holders both feature a brass compression ring, so your eyepiece barrels will not be scratched by the set screw. The 1.25"-2" adapter is also threaded to accept 2" filters. The diagonal comes in a very nice foam-fitted storage box and includes 2 end caps. Made in Taiwan.
We also sell an optional 2" SCT barrel that will allow you to use this refractor diagonal with SCT or Mak telescopes with a standard SCT male thread. With this accessory, there
is no need to buy another SCT diagonal and the same diagonal can be used with both types of telescopes!
