- Economical 2" refractor diagonal with 92% reflectivity across visible spectrum
- Glass mirror polished to 1/10-wave for bright and true images
- All-metal body with chrome barrel threaded for standard 2" filters
- Comes with 2"-1.25" eyepiece adapter for maximum flexibility
GSO's 2" refractor mirror diagonal is an excellent alternative to higher priced diagonals for those on a budget or just getting started in the 2" format. This diagonal features Al + SiO2 coatings with 92% reflectivity across the visible spectrum and a 1/10 wave mirror. This GSO diagonal offers excellent mechanical and optical quality at a great price.
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 clear aperture is 46.6mm.
Includes 2 end caps. Weight = 1lb-5oz. (with 1.25" adapter); 1lb-2oz. (without 1.25" adapter). Made in Taiwan.
Please note: Even though the eyepiece holder and the 2" nosepiece of this diagonal have standard SCT (2"x24TPI) threads that will work with other SCT threaded items, the threads on the body of the diagonal are NOT standard SCT threads. The thread diameter on the diagonal body is 2" but the thread pitch is very slightly different (not 24TPI) and has not been specified. GSO ensures that these components that they machine fit together, but SCT-threaded adapters from other brands will not thread on properly or at all to GSO's 2" diagonal bodies in most cases due to this marginally different thread pitch.
