Product Description & Reviews

Orion has given their 2 inch dielectric mirror diagonal a new twist - literally! With its twist-tight clamping mechanism, the Orion 2 inch Dielectric Twist-Tight Mirror Star Diagonal presents a significant upgrade from typical thumbscrew-equipped diagonals. A simple clockwise twist of the diagonal's knurled red aluminum collar precisely centers any inserted eyepiece or accessory and holds it securely in place. The innovative twist-tight mechanism keeps your valuable eyepieces free of pesky thumbscrew scratches, and also provides a more secure grip than thumbscrew-equipped diagonals. You'll especially appreciate the Orion 2 inch Dielectric Twist-Tight Mirror Star Diagonal when using a telescope during clear, cold evenings thanks to how easy it is to tighten and loosen the large, knurled collar - even while wearing bulky gloves! Built around a highly reflective mirror featuring lab-tested dielectric coatings that provide an astounding 99% reflectivity, the Orion 2 inch Dielectric Twist-Tight Mirror Star Diagonal will help you obtain the brightest views possible through a refractor or Cassegrain telescope equipped with a big, 2 inch focuser. Plus, since dielectric coatings are more durable than enhanced aluminum coatings, you'll enjoy year after year of exceptional performance without degradation. To further optimize contrast and brightness, the diagonal's anodized aluminum housing features machine-threaded internal baffles to eliminate pesky internal reflections and glare. The versatile Orion 2 inch Dielectric Twist-Tight Mirror Star Diagonal includes a handy 1.25 inch adapter, so it can be used with both 2 inch and 1.25 inch telescope eyepieces. Both the 2 inch holder and 1.25 inch step-down adapter feature a twist-tight collar. Protective caps are included to keep the diagonal free of dust when not in use. Please note: diagonals are not recommended for use with Newtonian reflector telescopes
