The Altair-EX Dielectric Diagonal is precision CNC machined with an extremely reflective, accurate and smooth mirror surface for maximum image contrast. Recommended to do justice to telescopes with good quality optics.
 
The multi-layer dielectric coatings are so incredibly reflective, it's difficult to see the actual mirror surface when looking into a newly purchased diagonal. Dielectric coatings are more durable than aluminium ones because they do not oxidise, and are extremely scratch resistant, therefore easier to clean.
 
The 2" barrel is threaded for filters, and it has an internal blackened thread to stop stray light reflection, increasing image contrast. A precision machined low profile 1.25 to 2" eyepiece adapter with brass compression ring is also included, which will not mar your eyepiece barrels. The low profile adapter has a corresponding slot machined into the diagonal body to lower it even further. This achieves as much infocus possible for Cassegrain users who would like the focal length of their telescope to stay as close to design parameters as possible.
 
The Diagonal comes with a durable hard presentation box with protective foam insert, and two plastic end caps.
