The Regal 100ED from Celestron’s M2 series. These series offer mid-range and some expensive spotting scope. M2 series is well known for their superior optical quality and solid construction. They are ideal for long distance viewing, target practicing, and birding because image quality remains intact even at the highest magnification. Regal 100ED brings all the feature of other M2 series scope and some other advanced features (which we will discuss here) at a price that is neither cheap nor expensive, basically a great mid-range scope.
As the name suggests Regal M2 100ED features a 100mm ED glass for an objective lens where ED stands for Extra low Dispersion Glass. A feature that is mainly found in some highly expensive scopes priced above 1000 dollars. Light is made up of different Wavelengths when it passes through lens different wavelength behave differently, resulting in a mismatch at the focal point and causes blurred or color distorted image this phenomenon is called a Chromatic aberration. Presence of ED glass in Regal M2 scope limits the scattering of light as it passes through the objective lens and focuses them to the center of eyepiece. This results in sharp, clear and better contrast image with minimum color distortion.
To further enhance the viewing capability Celestron is using its proprietary XLT coating (fully multi coated optics). There is basically four type of lens coating, a single layer Coating (C), a single layer on all air-to-glass surfaces also known as Fully Coating (FC), A Multilayer Coating (MC) and fully multi Coating (FMC). Celestron is using the most expensive Fully multi coated XLT coating in their Regal M2 100ED scope where multiple layers of hafnium oxide (HfO2), titanium dioxide (TiO2), silicon dioxide (SiO2), and magnesium fluoride (MgF2) coating is done on all air to glass surface to maximize light transmission through optical path for better high resolution, high contrast images even in low light condition.
Eyepiece & Focusing
Celestron Regal M2 100ED scope includes a 22-67x adjustable magnification zoom eyepiece which gives the user a wide field of view for general purpose at 22x and magnified close up view above that magnification.

If you love astronomy and have some extra telescope eyepieces (1.25”) in stock you can also use them with this scope for some extra power.
