Coronado SolarMax III 70mm Solar Telescope With Richview System & 15mm Blocking Filter

The SolarMax III is a 70mm f/5.7 refractor with a 70mm external hydrogen-alpha (Ha) filter.  This is a single-stacked option with a 15mm blocking filter.

The SM3 70mm has a new two-speed rack & pinion focuser, creating a more user-friendly interaction with the telescope. The two-speed, 2” focuser has coarse and fine focus controls allowing you to get a more precise focus, which is critical for solar imaging and visual observing.

Additionally, the SM3 70mm includes only external “True” Ha etalon filters giving higher contrast views and sharper features compared with models using smaller internal Ha etalon designs. Experience darker backgrounds, sharper features, and higher contrast with the new SolarMax III telescope.

The SM3 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 a better way of adjusting the filter 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 favourite solar features without sacrificing image quality.

The new Coronado 70mm SolarMax III telescope with enhanced rack & pinion focuser and large external etalon(s) are now the perfect way to view the Sun! The SM3 70mm comes with an included 18mm CEMAX eyepiece, Sol Ranger™ Solar Finder, Vixen-style dovetail mounting rail, and an all-new black and gold colour aluminium Hard Carry Case (Dimensions: 67cm x 22cm x 22cm / 26.5" x 8.66" x 8.66").

Coronado assures that all solar filters are tested at accredited labs to verify compliance with the ISO 12312-2 safety specifications for solar viewing.
