SharpStar 130 mm F/2,8 HNT hyperbolic astrograph with corrector and carbon tube (SKU: 130F2.8HNT)

SharpStar 130mm F/2.8 Hyperbolic Newtonian Astrograph with Corrector and Carbon Fiber Tube

Experience the pinnacle of astrophotography with the SharpStar 130mm F/2.8 Hyperbolic Newtonian Astrograph. Designed like the Formula 1 of telescopes, this astrograph offers unmatched speed and precision, perfect for capturing the cosmos in stunning detail. Its ultra-fast f/2.8 optics and state-of-the-art carbon fiber construction set a new standard for astronomical imaging.

Advanced Optical System

This exceptional astrograph features a hyperbolic Newtonian reflector with a 130mm aperture and a 364mm focal length, ensuring exceptional light-gathering capabilities. The primary mirror, crafted from PZ33 glass, boasts a low coefficient of thermal expansion similar to Pyrex, and is enhanced with a high-efficiency dielectric coating that reflects up to 97% of incident light.

Innovative Corrector Design

The integrated field flatness corrector is essential for delivering sharp, distortion-free images. This component includes a doublet with an air gap made from low-dispersion (ED) glass, ensuring high-quality optical performance across the field of view.

Precision Engineering

The SharpStar 130mm F/2.8 HNT is not only about optics; it’s also engineered for durability and precision. Its robust rack & pinion focuser supports even the heaviest of astronomical cameras, while the CNC-machined mounting rings and Losmandy rail guarantee stability and balance for the tube.
