Celestron Ultima ED Refractor 100ED 45° is a powerful spotting scope with Extra Low Dispersion (ED) glass and comes with a 10 year Warranty

 
 
Celestron's Ultima 100 ED spotting scope offers 50% brighter images than the 80mm, allowing for better performance in low light conditions. Like the Ultima 80ED, the 100 mm version is a high performance model that features cutting edge optics with extra low dispersion glass (ED). ED glass provides excellent colour correction and razor sharp images for serious nature and bird watchers.

ED version models are also ideal for virtually eliminating chromatic aberration usually seen during planetary and lunar viewing. Day or night, this scope is optimized to provide the sharpest images available. Model also features charcoal color rubber textured paint for secure grip.
