Coronado 70 SolarMax III Solar Telescope W/ RichView Tuning - 15 mm Blocking Filter
This Coronado 70 mm SolarMax III H-Alpha Solar Telescope is the latest addition to the famous Coronado SolarMax line-up! The 70 mm refractor has a 400 mm focal length, or f/5.7. It's equipped with a 60 mm external H-alpha etalon, which yields higher contrast, sharper images than a scope using a smaller internal etalon. That external etalon is complemented by a 15 mm blocking filter permanently incorporated in a 1.25" star diagonal. Together, the tunable external etalon and blocking filter yield a bandwidth of < 0.7 Angstrom which provides an optimum visual balance of solar prominence and surface detail.
You tune the etalon with Coronado's patented RichView Tuning. The revolutionary RichView™ tuning method allows you to zero in on the most precise wavelength of light for each area on either side of the hydrogen-alpha (Ha) band. You will see the highest contrast views of active regions, flares, filaments, and other features on the Sun's surface. With RichView you can also retune the SolarMax III quickly and easily for spectacular images of prominences on the solar limb. This wide range of tuning accuracy in the SolarMax III from Coronado makes it an industry leader.
The SolarMax III includes a 2" rack and pinion (R&P) focuser that has dual-speed 10:1 fine focusing. The coarse and fine focus adjustments will be appreciated when you are looking for that fine detail of events occurring on the Sun.
You will stand out from the rest at your solar observing gathering. The Coronado 70 mm SolarMax III H-Alpha Solar Telescope is not only a fine optical instrument to look through, but is also impressive to look at! The polished brass and black anodized components provide a nice contrast, so this scope has a beautiful, classy look you will appreciate every time you use this scope.
You can mount the 70 mm SolarMax III Solar Telescope by Coronado on any sturdy mount that accepts a Vixen-Style dovetail. Coronado sells a matching alt-azimuth mount and tripod that would work well for visual observing, since this solar telescope only weighs 7.6 pounds. (For doing solar photography, a more substantial mount would be helpful.)
