Discover the universe with the Explore Scientific ED102 Essential Series Air-Spaced Triplet APO Refractor Telescope, a true apochromatic instrument that unveils the lunar landscape's dramatic craters, Jupiter's neatly striped atmosphere, and the dazzling stars of the Orion Nebula set against its nebulous home. This apochromatic refractor opens up a universe of celestial wonders, laying a firm foundation for beginning deep sky astrophotography.

Striking a perfect balance between portability and aperture size, this high-performance telescope is engineered for sharp, diffraction-limited observations across a broad range of celestial objects. Whether it's the moon, planets, or deep sky phenomena, its objective lens delivers outstanding clarity and detail.

The telescope's air-spaced triplet optical design significantly reduces chromatic aberrations, producing vibrant, high-contrast images. This is achieved through the use of authentic HOYA FCD1 extra-low dispersion (ED) glass and our exclusive EMD enhanced multi-layer coatings, ensuring unparalleled optical quality.

This model comes with two extension tubes for its 2" rack-and-pinion focuser, and the Explore Scientific 2N1 Finder Scope Base comes pre-installed on the telescope. (Note: Finder scope is not included. Enhance your viewing experience with the addition of the Explore Scientific 8x50 Straight Through Illuminated Viewfinder or the Explore Scientific 8x50 Illuminated Right Angle Polar Finder Scope.)
