Small Wonder: Astro-Tech 1¼-inch Diagonal

S&T: Craig Michael Utter
In recent years it seems that all the emphasis has been on 2-inch eyepieces and accessories, leaving the venerable 1¼-inch “standard” in the shadows of the amateur marketplace. But no longer. Astronomy Technologies, or Astro-Tech for short, has incorporated most of the latest features found on premium 2-inch diagonals in a classic 1¼-inch design ($69.95). A 46-layer, ion-deposited dielectric coating on the diagonal’s 1/10-wave mirror delivers 99% reflectivity, while the machined-aluminum housing with a brass compression-ring lock for the eyepiece adds to the solid construction. The diagonal’s nosepiece is threaded for standard 1¼-inch filters and accessories.
