SharpStar 13028HNT-AL Hyperbolic Newtonian Reflector (13028HNT-AL)

SharpStar 13028HNT-AL Hyperbolic Newtonian Reflector (13028HNT-AL)The 13028HNT AL is a hyperbolic Newtonian reflector with a 130mm aperture and a fast F2. 8 focal ratio. 13028HNT AL supports a 44mm full frame image circle, and the star performance is great. The primary mirror is made of Pyrex alike glass PZ33. The thermal expansion coefficient is smaller than ordinary glass. The dielectric multilayer coating gives the primary mirror a highly reflective ability of up to 97%. The minor axis of the secondary mirror is
