Celestron Ultima 100 Refractor

#C/52252

The Celestron Ultima 100 has a 100 mm refractor and 45 degree viewing angle, it has the largest aperture size in the Ultima series and boasts over 50% brighter images than its previous model because of it. The increase in aperture size on this model allows it to perform much better in low light conditions. It features multi-coated optics and comes fitted with a 22-66x zoom eyepiece. The Ultima 100 Refractor is waterproof and is able to be used in all extreme weather conditions, and performs well in all light conditions. The design of the Celestron Ultima 100 Refractor makes it ideal for viewing nature and for any long distance spotting - perhaps even astronomy. It has a sleek, contoured design which makes it easy to handle, and nice to look at. Its main objective lens permits the image to be very low in chromatic aberration, or colour fringing, and this feature places the achromatic Ultima as a benchmark in this regard.
