iOptron 1.25 Inch Dielectric Star Diagonal 6231 - Premium Telescope Accessory for Astronomy & Stargazing

iOptron 1.25" Dielectric Star Diagonal

The iOptron 1.25" 90º Dielectric Star Diagonal will greatly improve your observing experience by placing your head in a comfortable position when your refractor or catadioptric telescope is pointed at or close to the zenith. This diagonal generates above 99% incoming light transmission for brilliant high contrast images while the maximum resolution is preserved due to its dielectric hard-coated mirror with BK-7 optical glass.

Made with durability in mind, this Dielectric Star Diagonal boasts black anodized aluminum housing and is remarkably lightweight. The 1.25" barrel and eyepiece holder makes it suitable for use with the most commonly encountered size of focusers, drawtubes, and accessories. The eyepiece holder also features a brass compression ring to prevent eyepiece marring when locked in place. A built-in safety-stop provides protection for the mirror, ensuring lasting life.
