Coronado - Solar Filter Tuners

THE T-MAX IS NOT A FILTER OF ANY KIND. IT MUST BE USED IN CONJUNCTION
WITH A CORONADO H-ALPHA FILTER SYSTEM

Some events on the Sun,- notably active flares and coronal mass ejections
(CME), are extremely fast moving. If such features occur on the disc of the
Sun, their high velocity towards the observer results in their wavelength
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.
