Explore Scientific 102mm Essential Series Refractor OTA



When the designers at Explore Scientific set their sights on creating a top-quality apochromatic refractor that anyone would be proud to own, they decided on a traditional air-spaced triplet optical design in a rugged, adjustable lens cell. All materials had to be top-notch, so genuine Hoya extra-low dispersion (ED) Dense Fluor Crown (FCD1) glass was chosen, and then experienced craftsmen shaped and polished the elements that would form the foundation of a high-quality, true APO refractor.



All Explore Scientific ED102 Triplet APO Refractors are diffraction-limited at .25PV or better. Special EMD™ enhanced multi-layer coatings are deposited on all optical surfaces, and the result is bright, high contrast images with virtually no light scatter. Interferometric data on your newly purchased and registered Explore 102mm apochromatic refractor is available upon request after 6 months of ownership.Time restrictions apply; please contact Customer Service for more information.



While optics are definitely the most important component of any telescope, other features, like the focuser and the optical tube, play a crucial role in the design. Below you will find highlights on all of the ingredients used to create Explore Scientific ED102 Triplet APO refractors, including a very liberal warranty that speaks volumes about the confidence we have in our telescopes!




Explore ED102 Air-Spaced Triplet Refractor Highlights



  • The Explore Scientific ED102 Triplet telescope has a focal length of 714mm and an f/ratio of 7.



  • These 102mm apochromatic refractors have true APO optics 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.



  • Sending your Explore Scientific 102mm apochromatic refractor off to the factory is always an option, but is not required.



  • These 102mm apochromatic refractors come with a heavy-duty 2" dual-speed rotatable focuser and a 2" 99% reflective diagonal.



  • To attach your Explore Scientific ED102 Triplet telescope to a variety of mounts, Explore has included the "Vixen-style" dovetail at the base of the dual rings. The "Vixen-style" plate fits mounts made by Explore, Meade, Celestron, Vixen & others.



  • This Explore Scientific ED102 Triplet telescope weighs 11 lb. The tube assembly is 25.6" long and has an outside diameter of 102mm, or 4.01".



  • All Explore Scientific products come with a STAR Extended-Life-of-the-Product Warranty. Upon registration, this product will be under warranty for as long as it is manufactured, plus five years.
