Coronado SolarMaxIII
Hydrogen – alpha Solar Telescope!
The SolarMax III (SMIII) is a 90mm F/8.9 refractor equipped with 90mm external hydrogen – alpha (H-α) filters. Available in both single-stacked (<0.7Å) and double-stacked (<0.5Å) bandpasses and either 15mm or 30mm blocking filters. What makes the SMIII standout?
The SMIII 90mm 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 90mm includes only external “True” H-α etalon filters giving higher contrast views and sharper features compared with models using smaller internal H-α etalon designs. Experience darker backgrounds, sharper features, and higher contrast with the new SolarMax III series telescope.
RichView Tuning
The SMIII 90mm 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-α 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.
