With its true apochromatic performance with diffraction-limited optics and ample aperture this versatile model can showcase deep-sky delights like the edge-on Sombrero Galaxy with its distinct bulging center or the spiraling beauty of the face-on Pinwheel Galaxy as easily as it can reveal the intricacies of the moon's winding Hadley Rille.Featuring an air-spaced triplet optical design that virtually eliminates chromatic aberrations this telescope generates brilliant high-contrast images by combining genuine FCD1 HOYA extra-low dispersion (ED) glass and proprietary EMD enhanced multilayer coatings on all optical surfaces. The cradle rings feature a built-in handle sculpted for secure handling.
The top face of the handle is slotted to allow a 1/4-20 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. The telescope comes with the Explore Scientific 2N1 Finderscope Base installed; the Finderscope is sold separately.
