Coronado's versatile SolarMax II 60 60mm f/6.6 H-alpha Double-Stack Solar Telescope is calibrated for the hydrogen-alpha wavelength, and comes equipped with their RichView tuning system. This system allows direct adjustment of the primary etalon filter enabling it to be tuned up or down from the 6562.8Å wavelength for highlighting specific zones of the chromosphere and to compensate for Doppler shift that can pull prominences and other features off-band and affect views. Tuning areas of concentration back on-band, allows for higher-contrast views of prominences on the solar limb.

Its primary internal etalon provides a bandpass of 0.7Å which will reveal prominences in high contrast. Prominences generally appear larger with this size filter than in narrower bandwidths. This version of the SolarMax II comes with a secondary etalon that fits on the front of the OTA and narrows the bandpass to 0.5 Angstroms. At this bandpass, surface contrast is improved versus wider bandpasses. This ability to change the bandpass allows users to see more areas of the Sun than with a single-etalon solar scope. Complementing the etalon filters is a rear 90° 5mm blocking filter. This secondary filter further isolates the H-alpha wavelength to improve contrast and enhance views.

The SolarMax II is offered here without a mount or tripod, but comes with a wide clamshell mounting ring that is outfitted with a 1/4"-20 socket for attachment onto many photo/video/field tripods or on piggyback rigs, or an optional Vixen-style dovetail plate is available for use with conventional alt-az, EQ, or motorized telescope mounts.
