Manufacturer's claims (from Celestron)Show
- PREMIUM ED OBJECTIVE LENSES: Extra-Low Dispersion (ED) glass virtually eliminates chromatic aberration or color fringing, a visual defect common in binoculars. You'll enjoy razor-sharp images with outstanding, true-to-life color.
- XLT LENS COATINGS: All air-to-glass surfaces are multi-coated with Celestron’s proprietary XLT coatings – the same ones we use on our observatory-class telescopes. XLT maximizes light transmission through the optical path for brighter images.
- PERFECT VIEWING ANGLES: Use your spotting scope with the included 22-67x zoom eyepiece or any 1.25” astronomical eyepiece. Regal M2 ED’s rotating tripod mount allows you to position the eyepiece at the most comfortable viewing angle.
- FIELD-WORTHY ACCESSORIES INCLUDED: The Celestron Regal M2 100ED includes a padded view-through case, an objective cover, eyepiece cover, a T-mount adapter for attaching your DSLR camera for digiscoping, and more.
- UNBEATABLE WARRANTY & CUSTOMER SUPPORT: Buy with confidence from Celestron, a leading optics brand in California since 1960. Your purchase includes a Celestron Limited Lifetime US Warranty & US-based expert tech support.
