Description

Caution: This telescope should never be used to observe the Sun without the etalon filters and blocking filter (diagonal) fitted. Otherwise, immediate and irreversible eye damage may result.

The SolarMax III is a 70mm F/5.7 refractor equipped with 60mm external hydrogen – alpha (H-a) filters. This model is double-stacked (<0.5 Angstrom) bandpass with a 10mm blocking filter. What makes the SM3 standout?

Focuser

The SM3 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.

External etalons

Additionally, the SM3 70mm includes only external "True" H-a etalon filters giving higher contrast views and sharper features compared with models using smaller internal H-a etalon designs. Experience darker backgrounds, sharper features, and higher contrast with the SolarMax III series telescope.

RichView tuning

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 filter's bandpass. No other commercially available H-a 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.

Day and night

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!

Double stacked

This double stacked model (<0.5 Angstrom bandpass) includes two "True" external etalon filters. One etalon filter equipped with our 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.

Bundled accessories

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 aluminium hard carry case (Dimensions: 68cm x 22cm x 22cm).

Mounting options

Mounting options include the Meade DS-2000 mount (product code: DSM) with computerised AutoStar and GOTO technology.
