Orion Sirius ED100 EQ-G GoTo Refractor Telescope – Product Warranty: One year
Type of Product: Telescopes > Refractors
As numerous customers have shown, the ED100′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 GoTo mount that provides the stability and precision control needed to capture beautiful deep-sky images. The ED100 sports a multi-coated 80mm objective lens doublet of 600mm focal length (f/7.5). One lens element is crafted from extra-low dispersion (“ED”) FPL-53 optical glass from Japan. This high-grade glass greatly reduces the chromatic aberration that causes color fringing around bright objects in standard achromats. The 2″ Crayford-style focuser accepts both 2″ and 1.25″ accessories. Astrophotography and observing are made effortless by the Sirius EQ-G GoTo mount. The included GoTo hand controller contains a database of 42,900 objects.

Love the lighter mount, the ED100 is great for the price – it is a doublet but acts like a triplet in quality!
Wonderful package, I have had this for 2 years and can say for astrophotography it is simply awesome. For deep sky visual, it is a bit underpowered in light gathering but totally rules in GOTO astrophotography and planetary/lunar imaging with a webcam.
Great stuff Orion!
