RichView Tuning Assembly

The Coronado SolarMax II 90 Double Stacked Solar Telescope employs Meade's revolutionary RichView assembly. This patented system enables direct tuning of the primary filter etalon so you can tune for the highest contrast views of active regions, flares, filaments, and other surface detail. It also allows for fast and simple re-tuning for prominences on the solar limb.

Integrated Double Stack System

Featuring a fully integrated double stack system to enhances the scope's resolution, it does so by reducing the already narrow <.7 angstrom bandpass to an even narrower <.5 angstrom bandpass. This essentially delivers enhanced resolution and contrast for an optical view of the Sun that's absolutely stunning and will reflect in photos. 

The double stack system has the bonus advantage of being able to operate at a less restrictive < .7A bandwidth by simply removing the external etalon. In this way image brightness is increased, enhancing the visibility of fainter limb detail.
