Coronado SolarMax III 90 Double Stack Series

With RichView Tuning System.

Introducing Meade’s new and improved Coronado SolarMax III (SM3) Hydrogen – alpha solar telescopes!

“True” H-α Etalon Filters
Additionally, the SolarMax III 90 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 SolarMax III 90 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.

Day and Night
The etalon filter is equipped with our patented RichView tuner. Whether you are focusing on the solar edge or surface features in the chromosphere, the SolarMax III 90 is the solar scope for you. Since the etalon filter is now external to the telescope, you can easily remove it 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!

Note: This telescope should NEVER be used to observe the Sun without the Etalon Filter AND Blocking Filter fitted. Otherwise, immediate and irreversible eye damage may result.

Complete Package
The new Coronado 90 SolarMax III series telescopes with enhanced rack & pinion focuser and large external etalon(s) are now the perfect way to view the Sun! The SolarMax III 90 comes with 12mm, 18mm, 25mm CEMAX eyepieces, CEMAX 2x Barlow, Sol Ranger™ Solar Finder, Vixen-style dovetail mounting rail, and an all-new black and gold Aluminum Hard Carry Case.

Choice of Blocking Filter
The SolarMax III is a 90mm F/8.8 refractor equipped with a 90mm external hydrogen – alpha (H-α) filter. This single-stacked (<0.7Å) bandpass model is available with either 15mm or 30mm blocking filter. What makes the SolarMax III standout?

Two-Speed Focuser
The SolarMax III 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.
