Note:This telescope should never be used to observe the Sun without the Etalon Filter and Blocking Filter (diagonal) fitted. Otherwise, immediate and irreversible eye damage may result.
Introducing Meade’s new and improved Coronado SolarMax III (SM3) Hydrogen – alpha solar telescopes!
This SolarMax III is a 90mm F/8.8 refractor equipped with a 90mm external hydrogen – alpha (H-α) filter. This single etalon (<0.7Å) bandpass is available with a 30mm blocking filter. What makes the SM3 standout?
The SM3 90mm 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.

“True” H-α Etalon Filters
|
Additionally, the SM3 90mm includes only 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.

|
RichView Tuning
|
The SM3 90mm 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 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 90mm 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 (diagonal) fitted. Otherwise, immediate and irreversible eye damage may result.
