Orion 100mm ED Apochromatic Refractor.

Own a 100mm Apochromatic Refractor For Less Than £1,000.

Recently, Astronomy magazine ran a "buyer's guide" to portable 4" apochromatic refractors. All were impressive scopes, no doubt. But considering their price tags, which ranged from $2,695 (yes, that was the cheapest) to $3,595, you'd be excused if you didn't run right out and throw down your credit card for one.

Here's something more practical: our 100mm ED apochromatic refractor. Priced at just £649.00, it's by far the most jaw-dropping value in high-end refractors 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, and the 900mm focal length (f/9.0) is ideal for visual planetary and lunar study and excels for imaging work as well.

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.

The revolution in affordable apochromatic refractors continues with the Orion ED100. Order yours today.
