Coronado SolarMax 60mm Ha Filter w/TMax Tuner and 15mm BF

SolarMax 60 - 60mm aperture narrowband Ha Filter with TMax Tuner and 15mm blocking filter. Maximized for telescopes up to 1500mm

SOLARMAX 60:

The SolarMax 60 is Coronado's midsize H-A filter. The SolarMax 60 provides double the light intake of the SolarMax 40 and the bandpass of <0.7A like the SolarMax 90, but without the price tag. The SolarMax 60 is threaded to fit the TV Pronto and adaptor plates are available for a number of other quality telescopes. You can contact Coronado for details. The SolarMax 60 includes a T-Max 60 and requires one of four Blocking Filters to function as a system.

The Advantage of the T-Max:

Some events on the Sun, notably active flares and coronal mass ejections (CMEs), are extremely fast moving. When such features occur on the disc of the Sun, their high velocity toward the observer results in their wavelengths' being Doppler-shifted shorter than Ha. If the velocity is high enough, this wavelength could be outside the passband of the filter and the feature would not be observable. The T-Max allows the user to de-tune the SolarMax slightly to bring such phenomena into better visibility. The T-Max fits between the SolarMax and its adaptor plate. A simple rotary wheel movement accomplishes the tilt necessary to move the passband of the filter. Because of the filter's position at the front end of the telescope, this does not compromise the performance of the filter nor limit the Ha field of view, as is the case with rear mounted filters.
