Coronado® SolarMax II 90 with 15mm Blocking Filter

Solar observation at its finest.

The revolutionary RichView™ tuning method, built into every new Coronado SolarMax II brings solar viewing to a new level. Now you can zero in on the most precise wavelength of light for each area on either side of the hydrogen-alpha (Hα) band for the highest contrast views of active regions, flares, filaments and other surface features - or quickly retune for spectacular images of prominences on the solar limb. No other commercially available Hα telescope provides the tuning range and accuracy of the SolarMax II.

Choice of Blocking Filter

Coronado by Meade SolarMax II 90mm Solar Telescope with RichView system is available in two configurations of blocking filter: 15mm and 30mm. The incredible Coronado SolarMax 90 series telescopes are the largest H-alpha (Hα) telescope ever to be mass-produced and are now available with the patented RichView tuning system. This awesome solar observatory features a sub 0.7 angstrom bandpass.

Used around the world by serious solar enthusiasts and professional research facilities alike for observation of surface detail and prominences on the Sun in hydrogen-alpha (Ha) light. Powerful but very portable, this high resolution Solar Telescope offers dedicated visual observation of the Sun as well as high quality imaging.


Breakthrough in Solar Observation

The new Meade Coronado II represents a breakthrough in solar observing with the new and revolutionary RichView tuning assembly. This patented system allows direct tuning of the primary filter etalon. No other commercially available Hα telescope can provide the tuning range and accuracy of the SolarMax II.
