The Orion SkyView Pro 100mm ED apochromatic refractor is a complete equatorial observing package featuring the ED100 apochromatic refractor optical tube assembly paired with the venerable SkyView Pro equatorial mount/tripod â€" at an unprecedented low price.
The "ED100" delivers images remarkably free of chromatic aberration, thanks to its fully multi-coated 100mm objective doublet. It's crafted with one element of FPL-53 extra-low dispersion "ED" optical glass from Japan. The 100mm aperture gives it 56% greater light grasp than our ED80. And the 900mm focal length (f/9.0) excels at visual planetary and lunar study and imaging work as well.
Bright ED optics and a rock-solid mount. This scope packs a lot of performance for the price!
