Orion Sirius 8 EQ-G GoTo Reflector Telescope

Orion Sirius 8 EQ-G Reflector Telescope Package

To capture dramatic celestial portraits with a film or digital SLR or an astronomical CCD camera, you'll need a solid mount with excellent tracking and guiding capability and, ideally, a telescope with a large aperture and a focal ratio of f/6 or less. The Orion Sirius 8 EQ-G reflector fills the bill nicely.

With the GoTo controller on the Orion Sirius 8 EQ-G, you can command the telescope to swing to any of 13,400+ celestial objects selected from intuitive menus on the controller. Dual internal stepper motors then move the telescope at up to 3.4" per second right to your target object, tracking it while you observe or photograph it. With the built-in autoguider interface and periodic error correction (PEC) and an included polar scope for accurate polar aligning, you'll have an album full of killer astroimages in no time!

If visual observing is your primary interest, the Orion Sirius 8 EQ-G will provide years of wonderful views. At its heart is an 8" (203mm), center-marked parabolic mirror of 1000mm focal length (f/4.9). The tube features an upgraded 2" Crayford-style focuser with a 1.25" insert and drawtube tensioning knob.

Other features of the Orion Sirius 8 EQ-G include ten slew rates from 1.5x to 800x sidereal and large R.A. and Dec. locking levers. The tripod is remarkably sturdy, featuring extendable 1.75"-diameter stainless steel legs.

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. 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.
