Our new 1.25-inch 15mm and 20mm FMC Super Wide-Angle (SWA) eyepieces. These are identical to the eyepieces sold by major telescope companies at much higher prices. Beautiful high-gloss black anodizing. They also feature high-transmission multi-coatings on all air-to-glass surfaces, blackened lens edges, and knurled rubber grips. Both models are parfocal, so minimal focus adjustment is required when switching between focal lengths. Threaded for standard 1.25" filters. Apparent field of view is 72° for both models. Eye relief is 13mm and 16mm for the 15mm and 20mm SWA models, respectively. These eyepieces are a great choice for our binocular telescopes or your binoviewer. Each eyepiece comes with caps and a storage box.
