SharpStar 150mm f/2.8 HNT Hyperbolic Newtonian Astrograph (15028HNT)

The delicately pierced handle bar is completely made from CNC-manufactured aluminum, which can be used as a base for the attachment of other accessories. The new design of the telescope handle can aesthetically and mechanically cater to the demands of enthusiasts.

A three-element corrector is laid in the optical path, enabling the whole optical system to better achieve full-frame imaging and control the vignette. The standard 55mm back-focus and M48×0.75 thread tapped on the focuser thoroughly prepare the telescope for most stock imaging devices and make sure the item in the objective lens can be perfectly projected onto the focal plane.
