BulletPoint : D203F750 Mirror for Newtonian Reflector Astronomical Telescope
BulletPoint1 : The fast f/2.8 focal ratio arises from the integration of a 150mm hyperbolic primary mirror with enhanced aluminium coatings with 96% reflectivity. This type of mirror delivers reduced aberration and field curvature at the edge of the wide field of view. The large 70mm secondary mirror passes light through a three-element corrector lens to deliver a crisp, sharp, and bright image over the entire 44mm image circle with minimal chromatic aberration and outstanding field flatness.
BulletPoint2 : The SharpStar 15028HNT Hyperbolic Newtonian Astrograph is a compact 150mm f/2.8 reflector using an innovative optical design and multiple precision elements to provide a 44mm image circle that fills 36mmx44mm full-frame sensors with an ultra wide 6 degree field of view. This is the ideal instrument for astrophotographers looking to capture wide field deep sky targets with a super fast optical system.
BulletPoint3 : The SharpStar 15028HNT is engineered and constructed to be durable for field use, yet portable and lightweight enough to make it easy to mount and handle. The scope uses an 18"-long tube and CNC aluminium fittings for a precision fit and finish. The 2.5” dual-speed rack and pinion focuser is capable of handling larger cameras and accessories without slipping.
BulletPoint4 : The focuser also comes with a 1.25" eyepiece holder for using the scope with small format cameras or even with eyepieces for visual observing. The back focus is 55mm from the M48x0.75 threaded adapter so will readily come to focus when used with a wide 48mm camera-specific T ring (not included).
BulletPoint5 : 【Three Year Warranty】Buy with confidence from a California-based brand. Your purchase includes a comprehensive three-year warranty and unlimited access to our technical support experts located in California.
