The SolarMax III is a 90 mm Aperture f/8.8 refractor solar telescope equipped with 90 mm external Hydrogen–alpha (H-α) filters. This telescope is a single-stacked <0.7 Angstrom Hydrogen-alpha-line Bandpass with a 15 mm blocking filter.
The Coronado SolarMax III 90 mm H-alpha Solar Telescope 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, which is critical and helpful, for both solar imaging and visual observing.
Additionally, the SM3 90 mm 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. You will experience darker backgrounds, sharper features, and higher contrast with the new SolarMax III series telescope.
The SM3 90 mm 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 filter's 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.
The new Coronado 90 mm SolarMax III series telescope with enhanced rack & pinion focuser and large external etalon is now the perfect way to view the Sun! The SM3 90 mm comes with an included 12 mm, 18 mm, and a 25 mm CEMAX eyepieces, plus a CEMAX 2x Barlow lens. Also included in this telescope package are a Sol Ranger™ Solar Finder, a Vixen-style dovetail mounting rail, and an all-new black and gold Aluminum Hard Carry Case (Dimensions: 26.5" x 8.66" x 8.66") to protect your investment. Enjoy viewing the Sun as you never have before!
