This Coronado 70mm F/5.7 refractor is equipped with a single stack 60mm external hydrogen - alpha (H-α) filter at <0.7 bandpass and a 10mm blocking filter. What makes the SM3 standout? Read on!

The SM3 70mm has a new two-speed rack & pinion focuser. This 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 SM3 70mm includes an external "True" H-α etalon filter 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.

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 an overall better way of adjusting the filters bandpass. Now you can tune for the highest contrast views of your favorite solar features without sacrificing image quality.

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 the etalon filter is now external to the telescope, you can easily remove both the filter and and the 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 new Coronado 70mm SolarMax III telescope with enhanced rack & pinion focuser and large external etalon is 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 (Dimensions: 26.5" x 8.66" x 8.66"). This very high quality 70mm solar telescope features an 400mm focal length, f/5.7 focal ratio, and 10mm blocking filter.

CAUTION: Never look at the Sun, either directly or through a telescope, without a professionally made protective solar filter installed that completely covers the front of the instrument, or permanent eye damage could result.
