 Celestron Regal F-ED Telescopes The Regal Fluoro ED APO Spotting Scopes are the finest ever offered by Celestron! The APO optical design combined with fully multi-coated glass elements ensure the highest levels of contrast, color fidelity, and sharpness. Celestron’s Regal F-ED spotting scopes feature an air-spaced doublet, one element of which is made from the exotic mineral fluorite. The extra low dispersion from the fluorite provides excellent color correction and razor sharp images while virtually eliminating chromatic aberration. Day or night, Regal F-ED spotting scopes are optimized to provide the sharpest images available. You’ll love them for bird watching, nature observing, long distance viewing and casual astronomical observing. Because they are completely waterproof you can feel comfortable using them in extreme weather. The matte gray finish allows for subtle observation in any natural environment. Regal F-ED spotters are a great companion for any outdoor enthusiast. A major advantage is the standard 1.25-inch eyepiece fitting that allows astronomical eyepieces to be used with the telescope, opening up a range of options. For astronomers it means they can use their existing eyepieces as well as the one supplied. You can even use astronomical filters, the most useful being the polariser that will reduce the reflection from water, often allowing you to see the colours of waterbirds' legs, even when they are swimming. The 80mm Regal F-ED was reviewed in Bird Watching magazine by Matt Merritt who rated it very highly as a good all-rounder. |
