  • 1Description

The ED127 T3 127mm f/7.5 Apo Triplet Carbon Fiber Refractor Telescope from Explore Scientific is a powerful optical tube assembly that can be used to see detailed views of celestial objects from the Moon to deep sky objects like nebulae and galaxies. It is also portable enough to be used as a grab-and-go option over larger and heavier scopes or set up on a dual-mount rig for astrophotography/astroimaging. Using Extra-low Dispersion (ED) glass in a triplet lens configuration, with fully multi-coated optics, creates images that are clear and bright with true color rendition and a resolution of just 0.9 arcsec.

This version of the ED127 OTA is outfitted with a Starlight Instruments 3" rack-and-pinion dual speed focuser. Explore Scientific upgraded to this focuser to ensure full coverage of astrophotography gear with larger imaging sensors. The dual-speed configuration ensures ultra-precise focusing to properly split binary stars and resolve fine details single-speed focusers are unable to achieve. Its carbon fiber optical tube is temperature-resistant with reduced expansion/contraction due to temperature changes that can affect the fine focusing abilities under extreme fluctuations. The carbon fiber is durable while reducing the overall weight. The included hard carrying case protects the OTA during transportation and storage with custom-cut foam for the scope, diagonal, a finderscope, and eyepieces.

Optical Performance
  • 127mm objective lens
  • 952mm focal length
  • Focal ratio: f/7.5
  • Refractor-style optical design
  • Extra-low Dispersion (ED) glass corrects for chromatic aberration for true color fidelity and improved contrast
  • Triplet optical design further corrects chromatic aberration
  • Proprietary EMD enhanced multi-coatings on all optical surfaces
  • Resolution: 0.9 arcsec
Use and Handling
  • Starlight Industries 3" focuser
    • Large focusing tube ensures full coverage of larger imaging sensors for astrophotography equipment
    • Dual-speed mechanism to achieve tack-sharp focus
    • Rack-and-pinion system to comfortably carry heavier loads
  • Bracket for user-supplied finderscope
  • 2" 90° star diagonal included
  • Two 2" threaded extender-tubes provide additional back-focus range if required
  • 2" and 1.25" eyepiece adapter to use smaller barreled eyepieces/accessories
Construction Details
  • Carbon fiber optical tube eliminates focus change due to shrinking/expansion caused by temperature changes while reducing overall weight versus aluminum OTAs
  • Vixen-style dovetail plate for easy compatibility with a variety of mounts
  • Hard carry case included for safe storage and transport
