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 90mm F/8.9 refractor equipped with 90mm external hydrogen – alpha (H-a) filters. This model is double-stacked (<0.5 Angstrom) bandpass with a 15mm blocking filter. What makes the SM3 standout?

Focuser

The SM3 90mm has a 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 90mm 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.
