Hubble Hyperbolic Newtonian Astrograph Optics
Hubble Hyperbolic Newtonian Astrograph Optics
- Hubble Optics has a breakthrough Hyperbolic Newtonian Astrograph (HNA) optics for the wide-field visual observation and astrophotography.
- The combination of a lightweight sandwich hyperbolic primary mirror and a matching custom corrector provides excellent wide-field performance for both visual observation and astrophotography, with numerous advantages over existing solutions:
- Superb on-axis image quality, with a Strehl ratio greater than 0.99. Much better overall performance than a parabolic mirror with a Ross corrector.
- The HNA corrector will be initially available in 3.5-inch versions with a Hubble Optics lightweight-sandwich primary mirrors, 12-inch to 40-inch. The delivery time is about 2-8 months. The complete optical set includes a lightweight-sandwich hyperbolic primary mirror, a high-quality secondary mirror, and a matching custom corrector assembly.
