The ED80 80mm f/6 Carbon Fiber Refractor Telescope from Explore Scientific is a versatile optical tube assembly that can be employed as a simple grab-and-go primary telescope, as a large finderscope mounted to a larger scope such as a Dobsonian, 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.
