Coronado SolarMax III 60mm Richview Solar and Blocking Filter

This Coronado SolarMax III 60mm Solar Filter set with RichView tuning system includes a 60mm diameter primary Hydrogen-alpha etalon filter with sub 0.7 angstrom bandwidth and 10mm,15mm or 30mm blocking filter. The filter set is packed in a hard case to protect your investment.

The 60mm etalon includes Meade's patented RichView tuning, allowing direct etalon filter tuning. The RichView tuning system adjusts the distance between the etalon's parallel glass plates to achieve the perfect wavelength bandpass for the feature you are observing while maintaining precise optical alignment. This patented technology also enables the etalon to be used at high-altitude observing locations. The RichView system allows for better control of contrast over your H-a bandpass window. In addition to RichView tuning, the included T-Max Tuner will enable you to tune in the brightest image and remove any internal reflections. The RichView and T-Max combined offer unparalleled image tuning to get the best possible view of solar details!

The kit also includes a Coronado 10mm, 15mm or 30mm right angle Hydrogen-alpha blocking filter (BF), now in the SolarMax III design. This updated design includes a long 2" diameter nosepiece with a 1.25" eyepiece holder and a T-thread connection. The blocking filter is the second element in any Coronado H-alpha system and is just as crucial to your safety and the system's performance as the primary SolarMax etalon filter.

NOTE: The blocking filter CANNOT be used without a SolarMax etalon.

Blocking Filter

BF10: provides full disk image when used with telescopes having a focal length of 1,000mm or less.
BF15: provides full disk image when used with telescopes having a focal length of 1,500mm or less.
BF30: provides full disk image when used with telescopes having a focal length of 3,000mm or less.

Coronado filters are used worldwide by serious solar enthusiasts and professional research facilities alike. When properly and safely mounted on your high-quality refractor or other suitable telescope, this filter set enables observation and imaging of the amazing and ever-changing surface detail and prominences on the Sun in hydrogen-alpha light.

Not for use on truss-tube telescopes with open sides as unfiltered sunlight may be transmitted through the optical tube. Custom mounting of the etalon to your optical tube will be required. End-users will be required to contract a third-party company to machine any necessary adapters (adapters not included).

The stunning bright red views through a Coronado Ha telescope display astounding surface and limb detail. Features such as prominence, filaments, plages, and surface granulation are fascinating to observe, and many of these features can change shape over days, or even hours in the case of flares and edge prominences.

Designed and Manufactured in North America.
