Orion 8727 2-Inch Dielectric Mirror Star Diagonal

90 degrees 2" mirror diagonal features sophisticated, lab-tested dielectric coatings that provide an astounding 99% reflectivity.
Dielectric mirror coatings are more durable than enhanced aluminum coatings and provide higher reflectivity for maximum view brightness.
Machined and anodized aluminum housing features machine-threaded glare baffles for high contrast.
Nosepiece barrel is threaded to accept 2" Orion filters, a 2"-1.25" step-down adapter is included.
The diagonal is a great way to make nighttime viewing orientations through a refractor telescope more comfortable.

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.
