    Explore Scientific Essential ED127 APO Triplet Refractor


    Explore Scientific's Essential ED 127mm Apochromatic Refractor captures the most elusive jewels of the night sky, making it the perfect asset for astrophotography. Included is Starlight Instrument's 3" Feather Touch Focuser to deliver optimal focusing capabilities.


    The wide aperture and true diffraction-limited optics deliver stunning views of deep sky wonders such as the edge-on Sombrero Galaxy with its unmistakable bulging center, or the spiraling elegance of the face-on Pinwheel Galaxy just as readily as it can display the elaborate complexity of the Moon's winding Hadley Rille.


    For brilliant high contrast images, this telescope couples genuine HOYA extra-low dispersion (ED) glass with Explore Scientific's proprietary EMD enhanced multi-layer coatings on all optical surfaces. The Essential ED127 also uses an air-spaced triplet optical design to virtually eliminate chromatic aberrations. In addition, set-up is quick and easy, allowing observers to take advantage of their time under the stars by letting them spend more time at the eyepiece.
