Description
Coronado SolarMax III 70 Double Stack Solar Scope with BF15
The Coronado SolarMax III 70mm refractor stands as the ultimate tool for witnessing the captivating intricacies of our closest celestial neighbor. With its lightweight and compact design, accompanied by a robust hard-shelled carrying case featuring foam interior, this hydrogen-alpha (H-α) telescope becomes your companion for celestial exploration, whether it’s in your backyard or chasing the next solar eclipse around the globe.
Crafted as the flagship model of the 70mm line, it boasts a dual stack front etalon combined with the larger BF15 blocking filter, delivering unparalleled performance. The heart of this SolarMax III 70mm lies in its double-stacked system, comprising two external 60mm air-spaced etalons, offering breathtaking views of the solar spectrum’s most captivating segment—Hydrogen-alpha light (6562.8 Angstroms).
With a remarkable bandpass of <0.5 Angstroms (Å), this telescope ensures exceptional contrast for observing prominences, sunspots, filaments, active flare regions, plages, and surface granulation. Compared to the single-stack version, the ultra-narrow >0.5 Å bandpass of this system elevates contrast even further, enhancing surface detail exploration.
Ensuring safety for solar viewing, the integral 15mm blocking filter (BF15) includes multiple internal filters such as the Induced Transmission Filter (ITF), Long Wave Pass filter (LWP), and H-a cut-off filter. The BF15 offers a larger unvignetted area around the sun’s disk compared to the smaller BF10, accommodating features at higher magnifications or imaging with larger camera sensors.
Tuning the solar image for optimal contrast is facilitated by Coronado’s patented RichView tuning technology, alongside the T-Max Tuner, providing unparalleled image tuning for the best possible solar detail observation.
Moreover, the SolarMax III transcends solar observation, doubling as a versatile tool for night sky astronomy and daytime spotting. By simply unthreading the front etalons and substituting with a standard star diagonal, it transforms into a 70mm wide field doublet refractor, perfect for observing planets, star clusters, and brighter nebulae and galaxies.
Equipped with a backlash-free 2″ dual-speed rack & pinion focuser, Sol Ranger Solar Finder, and an 18mm CEMAX eyepiece, this telescope ensures precision and ease of use. Complete with a Vixen-style dovetail mounting rail and an all-new black and silver aluminum hard carry case, it’s ready to accompany you on your celestial adventures.
The SolarMax III 70mm telescope is not only a portable and versatile instrument for solar observation but also a gateway to capturing stunning displays of solar phenomena with a camera. Hand-assembled and solar-tested before being sealed in the box, it promises spectacular views that await your exploration.
Coronado guarantees adherence to safety standards, with all solar filters and telescopes tested at accredited labs to verify compliance with ISO 12312-2 specifications for solar viewing.
