SOLD - Explore Scientific 152mm f/4.8 Maksutov-Newtonian Comet Hunter
Selling my Explore Scientific 152mm f/4.8 Maksutov-Newtonian Comet Hunter. The scope and optics are all in excellent condition.

The David H. Levy Comet Hunter is a f/4.8 Carbon Fiber Maksutov-Newtonian; 99% Reflective Secondary Mirror; Two-Speed 2-inch Focuser; 1.25-inch Adapter and Extension Tube; Cradle Rings with Handle and Vixen-Style Dovetail.
The 6-inch f/4.8 Maksutov-Newtonian primary mirror is crafted from BK-7 glass, and layered with Explore Scientific's Enhanced Multi-Layer Deposition (EMD)coatings for bright, high contrast images and the elimination of light scatter. The addition of a Maksutov corrector plate improves off-axis images over traditional Newtonian optics. The EMD-coated corrector eliminates spherical aberration and produces those pin-point star images across the field. The secondary mirror, held in place by the corrector plate, is provided with 99% dielectric coatings for high reflectivity and protection.
The Comet Hunter has a Carbon Fiber Tube Assembly & Dew Shield, the high strength-to-weight ratio and low expansion characteristics of the material, which helps maintain focus despite fluctuations in temperature. The interior is painted flat black, and the primary is baffled to keep wayward photons from entering the optical path. On the exterior of the tube the focuser fits tightly and the primary mirror cell is sealed against light leaks.
The Explore Scientific Comet Hunter Focuser is a high quality precision 2" dual-speed Crayford-style focuser with 10:1 micro focus and tension adjustment.
