    Why Buy From Backyard-Planet

    Explore Scientific 9mm 120 Degree Argon-Purged Waterproof Eyepiece

    The Explore Scientific 9mm 120° Argon-Purged Waterproof Eyepiece Series is in a class by itself. The 120° apparent field of view is unlike anything you may have experienced before. Normally, when looking through hyper wide field eyepieces, you see a huge swath of the night sky at low magnification. With this 9mm 120 degrees eyepiece, however, you can see even more universal real estate. You also see the main attraction, whether it is a nebula, a galaxy, or a star cluster.  In our opinion, it is the best of both worlds.

    With such a wide field, you will also notice that objects stay in the field of view for a long time. It can be especially noticeable when your telescope does not include a drive, like a Dobsonian or a refractor on a "grab and go" mount like the Explore Scientific Twilight I. 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 averted vision is especially helpful when observing faint objects. Using averted vision puts the image on the part of your eye that is more sensitive to light, allowing you to see more indistinct images.
