Product Highlights

  • 127mm Aperture Refractor OTA
  • 952mm Focal Length, f/7.5 Focal Ratio
  • Hoya FCD100 Anomalous ED Glass
  • Apochromatic Triplet Lens System

The ED127 127mm f/7.5 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 multicoated optics, creates images that are clear and bright without distortion across the entire field of view, with true color rendition.

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. A 2" 90° star diagonal is included for comfortable viewing and aids in viewing objects approaching the zenith.
