Explore Scientific 102mm f/7 Essential Series APO Triplet Refractor - No Case


From our Moon’s chiseled craters to Jupiter’s orderly cloud belts to the blue-white stars of the Orion Nebula popping against the complex misty cloud they call home, Explore Scientific’s 102mm Apochromatic Refractor can open up a treasure trove of night sky treats.

A nice compromise between portability and aperture, this versatile high-end telescope offers true diffraction-limited optics and has an objective lens size that performs well in lunar, planetary and deep sky viewing situations.

Featuring an air-spaced triplet optical design that virtually eliminates chromatic aberrations, this telescope generates brilliant high-contrast images by combining genuine HOYA extra-low dispersion (ED) glass and proprietary EMD enhanced multi-layer coatings on all optical surfaces.

Questions & Answers

Product Questions

Does the focuser on this scope rotate; does it have a tension adjustment on it; and/or a lock to hold it in place for astrophotography? Is there any difference between the optics and hardware on this scope vs the ES-EDT-10207-CF you also sell? Thanks.
