More information

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 65mm, enabling sufficient illumination for full-frame imaging.

The corrector in the focuser adopts a doublet lens design, one of which is an ED glass, enhancing the power in aberration correction.
