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

    The Orion Sirius ED80 EQ-G GoTo Refractor Telescope sports a multi-coated 80mm objective lens doublet of 600mm focal length (f/7.5). One lens element is crafted from extra-low dispersion, or "ED" optical glass. This high-grade glass greatly reduces the chromatic aberration that causes color fringing around bright objects and loss of sharpness in standard achromats.

    The ED80 refractor telescope's 2" Crayford focuser accepts both 2" and 1.25" accessories and has a drawtube tensioning knob for securing your camera position when imaging and your telescope eyepiece/diagonal assembly when observing.

    With the Sirius EQ-G mount and GoTo hand controller you'll experience effortless computerized navigation to over 42,000 celestial objects with a few button pushes 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 astroimaging adventures!

    The tripod features extendable 1.75"-diameter stainless steel legs and a cast-metal spreader plate/accessory tray for unflinching stability. To power the mount you will need a 12-volt DC battery or an AC-to-DC adapter for use of 110-volt power.

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