Explore Scientific ED152 152mm f/8 Triplet Carbon Fiber Refractor Telescope

Explore Scientific ED152 152mm f/8 Triplet Carbon Fiber Refractor TelescopeThe Explore Scientific ED152 puts 152mm of apochromatic triplet optics in a carbon fiber tube that weighs just 20. 5 pounds light enough for mid range equatorial mounts, powerful enough to resolve fine planetary detail and pull in faint deep sky structure. Its air spaced triplet design with HOYA FCD1 extra low dispersion glass delivers color corrected, high contrast views across the full field, whether you're splitting tight doubles or imaging

The Explore Scientific ED152 puts 152mm of apochromatic triplet optics in a carbon fiber tube that weighs just 20.5 pounds — light enough for mid-range equatorial mounts, powerful enough to resolve fine planetary detail and pull in faint deep-sky structure. Its air-spaced triplet design with HOYA FCD1 extra-low dispersion glass delivers color-corrected, high-contrast views across the full field, whether you're splitting tight doubles or imaging nebulae.

Key Features

• 152mm of light-gathering power — collects 44% more light than a 127mm and 125% more than a 102mm, revealing fainter detail in galaxies, nebulae, and star clusters
• HOYA FCD1 ED glass triplet — air-spaced apochromatic design with EMD enhanced multi-coatings virtually eliminates chromatic aberration for sharp, true-color views
• Carbon fiber tube — 20% lighter than an equivalent aluminum OTA with very low thermal expansion, so the scope reaches thermal equilibrium faster and stays in focus longer
• Dual-speed 2.5" HEX focuser — 10:1 fine-focus ratio with 360-degree rotation and tension adjustment locks down precise focus even under heavy imaging payloads
• 0.75 arcsecond resolution — resolves Jupiter's cloud belt detail, Saturn's Cassini Division, and tight binary pairs at the theoretical limit for this aperture
• 50.8mm image circle (76mm with 3" adapter) — wide enough for full-frame sensors when paired with the appropriate field flattener
• Losmandy-style dovetail and cradle rings — secure, vibration-free mounting with a built-in carrying handle

Ideal For

• Serious astrophotographers stepping up to a large-aperture refractor without the weight penalty — at 20.5 lbs the ED152 pairs well with mounts like the Losmandy G11 PMC-Eight
• Advanced visual observers who want a refractor that can reveal planetary detail, resolve globular clusters, and show structure in emission nebulae that smaller scopes cannot
• Astronomy clubs and educational institutions looking for a durable, high-performance instrument that's portable enough for star parties and outreach events

Accessories & Compatibility

The ED152 ships with a 99% reflective 2" dielectric diagonal, compression ring eyepiece holders in both 2" and 1.25", a hybrid 2N1 finder base compatible with most finder scopes and red dot sights, and a removable carbon fiber dew shield. The cradle ring system includes a Losmandy-style dovetail plate and integrated carrying handle.

For astrophotography, pair with the Explore Scientific 3" Field Flattener / 0.7x Focal Reducer for flat, distortion-free images across the full field. Upgrading to the Explore Scientific 3" Self-Centering Focuser adds additional payload capacity and zero-tilt precision for heavy camera rigs.
