The Coronado Personal Solar Telescope and their Solarmax II with Richview Tuning have been the most popular Hydrogen-Alpha Solar Telescopes sold to date. They have allowed people to observe the solar surface in detail that once would have been exclusively for professional or semi-professional astronomers only given the once high-cost of these instruments. Now Coronado have released their new SolarMax III 70mm Hydrogen Alpha solar telescope series at a still really affordable price.
The SolarMax III (SMIII) is a 70mm F/5.7 refractor equipped two “True” external etalon filters. One etalon filter equipped with Coronado's 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!
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-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 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-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 70mm SolarMax III series 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 Aluminum Hard Carry Case.
This very high quality 70mm solar telescope features an 400mm focal length, f/5.7 focal ratio, and 10mm blocking filter.. Includes mounting rings, Cemax 18mm eyepiece, Sol Ranger solar finder and black & gold aluminum hard carry case.
