100° Series 3" 30mm Waterproof Eyepiece

Sale price$1,259.99

The Explore Scientific 100° Series eyepieces are hyper-wide class oculars that can transform your visual astronomy experience. You may be startled at the amazingly wide expanse of inky black sky you behold the first time you bring your eye to a 100° Series eyepiece, and after awhile, you may even forget that you have an eyepiece between you and the universe! With an apparent field of view that is close to the maximum for hyper-wide eyepiece design, objects are not only easier to locate, but for non-driven telescopes the object will stay in the field of view for a very long time before any adjustments need to be made.

Another great benefit of hyper-wide eyepieces is the ease with which you can gaze, not directly at an object, but slightly to either side. This skill, called using averted vision, is especially helpful when observing faint objects, because using averted vision puts the image on a part of your eye that is more sensitive to light, allowing you to see fainter images.

  • 3-inch eyepiece
  • Huge apparent field of view gives a panoramic visual experience and also relaxes the eye so you can pay attention to subtle details for extended periods.
  • Each 100° Series Argon-Purged Waterproof eyepiece is internally sealed and purged with inert, dry argon gas.
  • This also maximizes the life of the internal coatings.
  • Every 100° eyepiece is tested by submerging them down to 1 meter of water for 30 minutes.
  • All 100° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

What people like

The Explore Scientific 100° Series 3" 30mm Waterproof Eyepiece is a monumental, observatory-class ocular that offers one of the most immersive and expansive panoramic views available in modern amateur astronomy. Expertly crafted with eight optical elements and argon-purged for complete waterproof and fog-proof integrity, this massive eyepiece creates a breathtaking "spacewalk" effect that makes the hardware seemingly disappear between the observer and the cosmos. Its specialized 3-inch barrel design allows for a colossal 52.2mm field stop, ensuring that large-scale celestial structures like the Rosette Nebula can be viewed in their entirety with stunning contrast and edge-to-edge sharpness.
