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.
  • Meets or exceeds the polychromatic performance of a parabolic mirror with a Wynne corrector, with much fewer problems from ghosting, baffling, and reflections.
  • Excellent optical performance for both wide field visual observation and astrograph at an unprecedented price/performance ratio.
  • 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.
  • Our 2-stage Truss Tube OTA is optimized to minimize the thermal focal shift

The HNA corrector

HNA 2-element 99.5% broadband AR coating 3.5" corrector assembly: $1000


Stocked HNA Optics

All our stocked mirrors are the same high quality mirrors as our standard mirrors (1/10 or better in PV, about 1/50 in RMS, and 0.95 or better in Strehl ratio, with the 96% enhanced aluminum coating free of extra charge).

The mirrors will be shipped from Hong Kong. The air shipping will take about 10+ business days, while the surface will take about 10+ weeks. The secondary mirror is not included in the prices.
