Orion 8880 1.25-Inch Dielectric Mirror Star Diagonal

90 diagonal features sophisticated, lab-tested dielectric coatings that boast an astounding 99 percent reflectivity.
Dielectric mirror coatings are more durable and more reflective than enhanced aluminum coatings.
Diagonal provides a comfortable 90-degree viewing orientation when observing the night sky through a refractor, Maksutov-Cassegrain (Mak-Cass) or Schmidt-Cassegrain telescope.
Machined and anodized aluminum housing features machine-threaded baffles for optimized contrast.
1.25" nosepiece barrel is threaded to accept like-sized Orion eyepiece filters.

Twin-tip technology with 11 mm platinum center electrode and 11 mm titanium enhanced ground electrode.
Improve fuel economy, better acceleration and faster starts than all other single platinum plugs.
Purified alumina powder insulator provides exceptional dielectric strength and thermal conductivity, allowing the material to stand up to extreme stress.

Enjoy better views through your telescope with this premium diagonal featuring diffraction-limited optics and dielectric coatings.
Provides a 90° viewing angle, perfect for more comfortable viewing through refractor and cassegrain-type telescopes.
58 layers of dielectric coatings provide an over 99% reflective surface, ensuring the maximum amount of light collected by the telescope reaches the....
Twist-lock keeps the eyepiece centered in the diagonal to provide better optical alignment.
Accepts standard eyepieces, Barlow lenses, threaded filters, and other accessories with a 1. 25” Barrel.
