Celestron SkyMaster 25x100mm Porro Binoculars

Celestron SkyMaster 25x100mm Porro Prism Binoculars

The Celestron SkyMaster 25x100mm Porro Binoculars are giant-aperture, high-power binoculars purpose-built for serious astronomy and extreme long-range terrestrial observation. With a massive 100mm objective lens paired with 25x magnification, these binoculars deliver exceptional brightness, resolution, and deep-sky reach that few handheld optics can match.

Now available from Modern Telescopes – India’s largest telescope and astronomy network, the SkyMaster 25x100 is a top choice for advanced amateur astronomers, observatories, astro clubs, wildlife professionals, and coastal surveillance users seeking maximum performance.

🌌 Extreme Light Gathering for Deep-Sky & Long-Range Viewing

The giant 100mm objectives pull in an enormous amount of light, making faint celestial objects easier to see even under less-than-perfect skies. From globular clusters, nebulae, galaxies, and comets to Moon craters and satellites, these binoculars provide bright, contrast-rich views with impressive limiting magnitude.

Paired with BaK-4 Porro prisms, the optical system delivers excellent depth perception, sharpness, and edge illumination across the field of view.

🔭 Precision Optics with Individual Eyepiece Focus

Unlike standard center-focus binoculars, the SkyMaster 25x100 features individual eyepiece focus, allowing each eye to be set precisely for maximum sharpness and focus stability—especially critical for high-magnification astronomy.
