Product Information

You could pay more than $2,500 for a premium 4&" refractor from one of those &"boutique&" telescope outfits, but here's something more practical: our 100mm ED apochromatic refractor. It's the best value in high-end portable refractors we've ever offered.
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. The 900mm focal length (f/9.0) is ideal for visual planetary and lunar study and also excels for imaging work.
The baffled, 36&"-long aluminum tube is outfitted with a 2&" Crayford-style focuser for exceptionally smooth focusing with no backlash. It accepts both 2&" and 1.25&" diagonals. A molded-in dovetail base accepts any Orion finder scope. Weighs 7 lbs.
