As numerous customers can attest, the short focal length and superb apochromatic optics of Orion's popular ED80 refractor make it a great telescope for astrophotography. And now Orion has coupled it with a state-of-the-art equatorial mount to provide the stability and precision control needed to capture beautiful deep-sky images.

This Orion 80 mm Sirius ED APO Refractor Telescope boasts a multi-coated objective lens doublet with 80 mm aperture and 600 mm focal length (f/7.5). One lens element is constructed using extra-low disperstion "ED" optical glass. With this high-grade glass, chromatic aberration is dramatically reduced to eliminate color fringing around bright objects and loss of sharpness experienced with standard achromatic refractors.

An included 2" Crayford focuser that accepts both 2" and 1.25" accessories features a drawtube tensioning knob to enable secure positioning for your camera while imaging, and for your eyepiece/diagonal configuration while observing.

With the Sirius EQ-G mount and GoTo hand controller you'll experience effortless computerized navigation to over 42,000 celestial objects with just a few pushes of buttons on the illuminated hand controller. Internal dual-axis stepper motors move the telescope at up to 3.4° per second right to your target object, tracking it while you observe or photograph it. Periodic error correction (PEC), a port for an autoguider, and an illuminated polar axis scope for accurate polar aligning are all standard features, designed to ensure successful astro-imaging adventures!

The tripod included in this package consists of 1.75" diameter stainless steel legs as well as a spreader plate and accessory tray made of cast-metal for enduring stability. Power options for this mount include a 12V DC battery or an AC-to-DC adapter for 110-volt power use.

For owners of the Sirius EQ-G GoTo Mount whose GoTo hand controller version is 3.0 or greater, the GoTo hand controller's firmware can be updated over the Internet.
