This externally mounted Polar Scope makes it easy to quickly align the Sirius Pro AZ/EQ-G Mount with the northern or southern celestial pole for accurate tracking and GoTo object location performance.
The Polar Scope features a rugged cast-metal mounting bracket complete with a built-in bubble level for accurate alignment. No tools are required for attachment, as the Illuminated Polar Scope utilizes captive knobs already built-in to the Orion Sirius Pro Mount head.
With a 20mm clear aperture and a dual-hemisphere reticle, the Orion Illuminated Polar Scope for Sirius allows swift and accurate polar alignment from any location in the world. An included illuminator device fits on the front of the Polar Scope to make the crosshair reticle easy to see at night. The illuminator is powered by a single button cell CR2032 battery (included). The reticle focus can be adjusted, as can the amount of illumination so you can choose how bright or dim the reticle pattern appears to match your preference.
The Orion Illuminated Polar Scope for Sirius Pro Mount weighs just 10.7 oz., and measures 6″ x 5.5″ x 2″.
