Explore Scientific Apochromatic Refractors

Explore Scientific apochromatic refractors are air-spaced triplets built for sharp, color-free views and imaging. The range includes the ED80, ED102, 127mm f/7.5 and ED152 tubes, in Essential Series or FCD100 Series versions, with carbon fiber or aluminum tubes and a 2.5" HEX focuser on the larger models.

Several bundles add a field flattener, a 0.8x focal reducer or an iEXOS-100 PMC-Eight equatorial tracker, so the ED80 and ED102 can serve as a complete portable imaging setup.
