Breakthrough HNA optics for wide-field visual observation and astrophotography. A lightweight sandwich
hyperbolic primary mirror paired with a matching custom corrector delivers superb on-axis image quality with
a Strehl ratio greater than 0.99 — far surpassing a parabolic mirror with a Ross corrector. Available from
12" to 40" with 2-8 month delivery.
Stocked Optics:
12" f/4.3 Pyrex Glass Sandwich Mirror with 3.5" Corrector
14" f/4.2 Plate Glass Sandwich Mirror with 3.5" Corrector
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 secondary mirror is not included in the prices.
