Explore Scientific 17MM 92 Degree 2" Long Eye Relief - Argon Purged

What this is, is a beautiful example of a wide field of view eyepiece with a luxuriously comfortable long eye relief- these two features combining for a truly immersive viewing experience when it comes to the majesty of the night skies- the comfort of the eye piece letting you forget that it's there- and the near maximum hyper-wide field of view almost letting you forget there's anything between you and the beautiful tapestry of the night sky and all it's stars. It's certainly a high quality eyepiece then, with it's broad field of view and extended eye relief ensuring that mix of comfort and practicality that can be called optimal. It's an ideal eyepiece to practice averted viewing with, as well; the wide field of view letting you look slightly to the side of faint items to see them better by allowing more sensitive parts of your eye to be what's focused towards them. And that's not all the broad field of view is good for! It also makes it easier to find objects in the night sky and keep them in your field of view for far longer without adjustment than eyepieces with lower FOV's can manage. All in all, it's a high quality example of a comfortable eyepiece- and certainly worth the investment to any interested in experiencing a wide field of view as they gaze upon the night sky in all it's beauty and majesty.
