Explore Scientific 102mm f/7 Essential Series APO Triplet Refractor - No Case
From our Moon's chiseled craters to Jupiter's orderly cloud belts to the blue-white stars of the Orion Nebula popping against the complex misty cloud they call home, Explore Scientific's 102mm Apochromatic Refractor can open up a treasure trove of night sky treats.
A nice compromise between portability and aperture, this versatile high-end telescope offers true diffraction-limited optics and has an objective lens size that performs well in lunar, planetary and deep sky viewing situations.
Featuring an air-spaced triplet optical design that virtually eliminates chromatic aberrations, this telescope generates brilliant high-contrast images by combining genuine HOYA extra-low dispersion (ED) glass and proprietary EMD enhanced multi-layer coatings on all optical surfaces.
- The Explore ED102 telescope comes with a white aluminum tube with black accents.
- Explore Scientific Air-Spaced Apochromatic Triplets have true APO optic and are diffraction limited at .25PV or better.
- Genuine ED glass from Hoya Japan is used on all ED APO Triplets at Explore, for superb quality and light throughput.
- Enhanced Multi-Layer Coatings (EMD) are deposited on optical elements to boost contrast and eliminate light scatter; and contrast is further enhanced with the installation of matte black knife-edge baffles in the optical tube assembly.
- 102mm models come with heavy-duty 2" dual-speed focusers.
- The included 2" diagonal has a precision-polished mirror with enhanced 99% dielectric coatings.
- To attach your Explore Scientific Air-Spaced Triplet telescope to a variety of mounts, we have included the "Vixen-style" dovetail. The "Vixen-style" plate fits mounts made by Explore, Meade, Celestron, Vixen & others.
- Aperture: 102mm (4")
- Focal Ratio: f/7
- Focal Length: 714mm
- Apochromatic triplet that is completely free of chromatic aberration
- ES 102mm Essential Series Apo Triplet Refractor OTA
- Heavy Duty 2" Dual Speed Focusers
- 2" Diagonal
- Vixen Style Dovetail
