Explore Scientific 100° Series Nitrogen-Purged Waterproof Eyepieces
Using advanced computer design, combinations of low dispersion and high refractive index optical glasses, and durable multilayer deposition coatings, Explore Scientific 100° Series™ hyper-wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics, and yes they are indeed ruggedized and waterproof to withstand the outdoor environment.
Apparent Field of View (AFOV)
The apparent field of view is the area of the sky that appears to be seen through an eyepiece.
Compared to other eyepieces, Explore scientific 82 and 100 degree AFOV eyepieces give you a much wider visual angle to scan your eye across the image inside the eyepiece. By scanning your eye from edge to edge you can more comfortably and naturally look into the eyepiece, and as you relax your eye, you begin to see finer and fainter details. This "immerses" you into visual experience of astronomy.
