EXPLORE SCIENTIFIC 9MM 100 DEGREE EYEPIECE – 2″
The 9 mm 100-Degree Eyepiece from Explore Scientific is a top notch, nitrogen purged, high-performance wide field eyepiece. Like all Explore Scientific eyepieces, the lens elements of the 100-degree eyepiece are meticulously cleaned and aligned before being installed in their precision machined lens barrels.
Each lens and lens grouping has EMD (Enhanced Multilayer Deposition) Coatings and is edge-blackened to eliminate light scatter and maintain image contrast. Contrast is further enhanced with baffles that mask and deflect unwanted stray light.
Each 100-degree Series Nitrogen-Purged Waterproof eyepiece is internally sealed and purged with inert, dry nitrogen gas to prevent internal fogging, to halt the intrusion of fine particulates and fungus, and to maximize the life of the internal coatings.
To make sure, every 100-degree eyepiece is tested by submerging them down to 1 meter of water for 30 minutes. Each and every Explore Scientific eyepiece is inspected both at the factory and again at our USA facility in California.
Explore Ultra-Wide Eyepieces – Comfort, Quality, Value. 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.
