Explore Scientific Essential Series 127mm f/7.5 Air-Spaced Triplet Refractor Telescope

 The ED127 127mm f/7.5 Essential Apochromatic ED Triplet Refractor Telescope from Explore Scientific features a triplet apochromatic lens system with Extra-low Dispersion (ED) glass and Explore Scientific's proprietary anti-reflection EMD fully multicoated optics.

Featuring an air-spaced triplet optical design it virtually eliminates chromatic aberrations and creates brilliant high-contrast images by combining genuine FCD1 HOYA extra-low dispersion (ED) glass and proprietary EMD enhanced multi-layer coatings on all optical surfaces.

The cradle rings feature a built-in handle, made for secure handling. The top face of the handle is slotted to allow a 1/4x20 bolt for attaching a DSLR for "piggyback" imaging. The bottom of the cradle ring includes a V-block (Vixen-style) plate for attaching to your equatorial mount.
