More Info

This add on etalon filter reduces the normal bandwidth of a PST, SolarMax 40 telescope, or filter set (etalon and Blocking Filter combination) from the single stack 0.7-1 Angstrom (�) performance to a more restrictive 0.5 �, increasing visibility of surface detail and active regions on the Solar disc. Note that this etalon cannot be used on its own — it MUST be combined with a primary SolarMax 40 filter and blocking filter, complete Coronado SolarMax 40 telescope, or a PST telescope.

Solar Disk Detail Image

The Sun in hydrogen-alpha light showing some of the different features visible around the solar disk.

Includes the patented RichView tuning assembly, which allows direct tuning of the primary filter etalon. This provides an optimized contrast boost for the best possible views of active regions, filaments and surface detail, or quickly and easily re-tune for prominences on the solar limb. Upgrade your PST or SolarMax 40 to a double stack configuration for an even more amazing view of our closest star!
