Product Highlights

  • Aperture: 70mm
  • Focal Ratio: F/5.7
  • Focal Length: 400mm
  • Blocking Filter Aperture: 10mm or 15mm
  • Wavelength: H-Alpha
  • Solar Filter: 60mm External H-Alpha Etalon

The SolarMax III (SMIII) is a 70mm F/5.7 refractor equipped with 60mm external hydrogen – alpha (H-a) filters. Available in both single-stacked (<0.7Å) and double-stacked (<0.5Å) bandpasses and either 10mm or 15mm blocking filters. What makes the SMIII standout?

The SMIII 70mm has a new two-speed rack & pinion focuser which creates a more user-friendly interaction with the telescope. The two-speed, 2” focuser has both coarse and fine focus controls allowing the user to get a more precise focus, critical for both solar imaging and visual observing.

Additionally, the SMIII 70mm includes only external “True” H-a etalon filters giving higher contrast views and sharper features compared with models using smaller internal H-a etalon designs. Experience darker backgrounds, sharper features, and higher contrast with the new SolarMax III series telescope.

RichView Tuning

The SMIII 70mm also includes Coronado’s patented RichView™ tuning allowing direct tuning of the primary etalon filter. The patented RichView™ tuning technology provides additional tuning range and an overall better way of adjusting the filters bandpass. No other commercially available H-a telescope can provide the tuning range and accuracy of the new SolarMax III telescope. Now you can tune for the highest contrast views of your favorite solar features without sacrificing image quality.

Double-Stack Option

Double Stacked models ((<0.5Å bandpass) include two “True” external etalon filters. One etalon filter equipped with our patented RichView tuner and second etalon with tip-tilt tuning using Coronado’s T-Max tuner. Whether you are focusing on the solar edge or surface features in the chromosphere, the SolarMax III 70mm is the solar scope for you. Since both etalon filters are now external to the telescope, you can easily remove both filters and rear blocking filter diagonal to use the scope as a normal refractor for night time astronomy. It’s like having two scopes in one!”

SAFETY FIRST: Observing the Sun without the proper protection may result in serious personal injury, including permanent eye damage and blindness, and/or damage to equipment. Never point an optic at the sun without an approved solar filter on the front of the optic. For direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder, ensure your filter is ISO 12312-2 (also written as ISO 12312-2:2015) certified. Never use photographic neutral density filters for direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder.
