This is the ultimate eyepiece! The 82-degree apparent field, edge-to-edge sharpness, and high contrast combine to deliver the most stunning views in all of amateur astronomy! Put the 31mm Nagler on your Schmidt-Cassegrain to get those hard-to-capture objects like the Andromeda Galaxy or the Pleiades star cluster. The 31mm Nagler on a short refractor makes for an incredible rich-field scope for scanning the Milky Way (don't forget a nebula filter to really pick out the wonders of our galaxy). On a big Dobsonian telescope the 31mm Nagler keeps the stars tack sharp to the edge of the field and is perfect for hunting down faint galaxies or searching for comets! Don't miss out on the ultimate window to the universe - get your 31mm Nagler today!
