    Orion Sirius 80ED EQ-G GoTo Refractor Telescope

    Orion Sirius 80ED EQ-G Refractor

    As numerous customers have shown, the Orion Sirius ED80's short focal length and superb apochromatic optics make it a great telescope for astrophotography. And now they'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 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 2" Crayford-style focuser on the Orion EQ 80ED accepts both 2" and 1.25" accessories and has a drawtube tensioning knob for securing your camera position when imaging and your eyepiece/diagonal assembly when observing.

    With the Sirius EQ-G mount and GoTo hand controller you'll experience effortless computerized navigation to 42,900+ 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 optional autoguider, and an illuminated polar axis scope for accurate polar aligning are all standard features, designed to ensure successful astroimaging adventures!

    The tripod which comes with the Orion Sirius 80 ED-G 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. One-year limited warranty.
