Orion Dielectric Mirror Star Diagonal 2-inch
|90-degree 2" mirror diagonal features sophisticated, lab-tested dielectric coatings that provide an astounding 99% reflectivity |
Our highest-quality 2" Orion Dielectric Mirror Star Telescope Diagonals feature sophisticated, lab-tested dielectric coatings that boast an astounding 99% reflectivity. Dielectric coatings are more durable than enhanced aluminum coatings, so you'll enjoy years of exceptional performance. The machined and anodized aluminum housing features machine-threaded baffles for high contrast and a nonmarring compression ring collar for securing the eyepiece. This 2" model has a 1.25" adapter to accept 1.25" telescope eyepieces. The diagonal's nosepiece barrel is threaded to accept 2" filters. Endcaps included.
Diagonals are not suitable for use with Newtonian reflector telescopes due to insufficient focus travel.
