The Orion 2” Dielectric Mirror Star Diagonal is not your average 90-degree diagonal. Featuring lab tested dielectric air to glass coatings it produces 99% reflectivity. This makes for high light throughput for increased brightness, producing high contrast and detailed viewing. Dielectric coatings are also more durable than enhanced Aluminium so you can expect years of usage without damaging wear and tear.

The Orion 2” diagonal is Ideal for any refractor or Cassegrain with a 2” focuser, however, it does feature a 1.25” adapter. This adapter will allow you to use all your favourite 2” and 1.25” eyepieces. The Machine anodized aluminium barrel increases viewing contrast via its threaded internal baffles, minimizing any internal reflections.

Never scratch any of your 2” or 1.25” eyepieces again with the built-in non-marring compression ring collar. Unlike most diagonals, the 2” nosepiece is threaded allowing you to swap between like-sized eyepieces without having to unscrew the filter every time you want to change the eyepiece. Orion includes protective dust caps so your items are protected from the elements when not in use.

The Orion 2” Dielectric Mirror Star Diagonal requires approximately 11cm inward focus travel relative to an eyepiece’s focus position without the diagonal.
