Upgrade Your Old Diagonal With a 2" Size
Celestron Dielectric Diagonal with Twist-Lock!

  • Enjoy better views through your telescope with this premium diagonal featuring diffraction-limited optics and 58 layers of dielectric coatings!
  • The Celestron 93573 Diagonal provides a 90Ā° viewing angle, perfect for more comfortable viewing through refractor and Cassegrain-type telescopes.
  • Dielectric coatings create a stunningĀ 99% reflective surface, ensuring the maximum amount of light collected by the telescope reaches the eyepiece.
  • Celestron orange twist-lock mechanism on the eyepiece side keeps the barrelĀ centered in the diagonal to provide better optical alignment.
  • The Celestron 2" Dielectric Diagonal accepts eyepieces, Barlow lenses, threaded filters, and other accessories with a 2ā€ barrel.
  • Caps are provided for both ends of the diagonal to keep these quality optics clean when they are not in use and stored.

The Celestron twist-lock eyepiece holder secures eyepieces while keeping them centered in the diagonal, thus providing best opto-mechanical alignment between the telescope and eyepiece. Unlike traditional thumb screws, the twist-lock cannot scratch or engrave the barrel of your eyepieces. This Celestron 2" Twist-Lock Dielectric Mirror Diagonal has an integrated 2ā€ barrel stop that prevents 2ā€ accessories with long barrels from damaging the mirror. All the diagonalā€™s mechanical parts are made of machined black anodized aluminum, except the twist lock rings, which are orange anodized for visibility.

The interior of the Schmidt-Cassegrain adapter and 2ā€ barrel are glare threaded and painted flat black to prevent unwanted reflections. With all its features and these high-end finishes, the Celestron Dielectric Star Diagonal, 2ā€ with Twist-Lock connection is a mirror diagonal which will serve your observing well for many years.

This diagonal also comes with two interchangeable barrels to provide flexibility in connecting the diagonal to a wide variety of telescopes without the need for additional adapters. A standard 2ā€ barrel is included. For Schmidt-Cassegrains (SCTs) that use a threaded connection to the focuser, a barrel with SCT threads is included. Both barrels thread onto the diagonal housing, providing a secure and safe connection.
