Product Highlights

  • 3mm-40mm Focal Length
  • 52° Apparent Field of View
  • 1.25" Diameter Barrel

Providing performance at a reasonable price for most beginners, the Explore Scientific 52° Series Eyepiece produces a moderate power in most telescopes, and is a perfect addition to your observation arsenal.

Outfitted with a generous 52° apparent field of view, it employs a flat-field lens system that is treated with their proprietary Enhanced Multi-Layer Deposition (EMD) coatings to produce bright and clear views that are flat edge-to-edge. This lens design makes this eyepiece ideal for averted viewing techniques in which you view dim deep sky objects, such as wispy nebulae, indirectly using the portion of the eye that is most sensitive to light.

This model of the 52° series is offered here with a standard 1.25" barrel to make it compatible with the most popular size drawtubes and accessories. The eyepiece is argon-filled and O-ring sealed to be waterproof against condensation and dew and resistant to fogging. A textured collar provides a slip-resistant grip, especially in cold weather or while wearing gloves. A fold down rubber eyecup makes it comfortable and easy to view through, with or without eyewear.
