The angled view Regal M2 100ED Spotting Scope from Celestron combines a high-transmission optical path with a nitrogen-filled magnesium alloy housing to deliver reliable imaging performance at low light and in unforgiving weather conditions. At the core of the Regal M2 are fully multicoated optics, including BaK-4 prisms and an extra low dispersion (ED) glass objective that minimizes chromatic aberration and maximizes light gathering. Multiple layers of Celestron's proprietary XLT coating on each lens preserve brightness and transmit contrast-rich images to the eyepiece.
This version of the Regal M2 spotting scope includes a 22-67x eyepiece that is ideal for intermediate to long-range glassing. The broad magnification range, comfortable 20mm eye relief, and twist-up rubber eyecup make this zoom eyepiece well-suited for long-duration observations. The scope's standard 1.25" eyepiece mount will accept most astronomy eyepieces, which enables a near-infinite number of optical configurations.
Complementing the image quality and weather-sealed construction of the Regal M2, several features enhance the scope's functionality and observer's user-experience. An included T-adapter ring permits DSLR camera mounting to the objective assembly, transforming the 100ED into a high-transmission digiscoping platform. The rotating tripod collar has a 1/4" mounting socket and is detented at multiple positions to provide the observer with alternate viewing orientations. A sliding sunshade, sighting aid, and dual-focus mechanism equip the Regal M2 with the functionality needed for a wide range of outdoor glassing applications.
