Coronado Solarmax Filter Kit with 40 H-Alpha .7A BF-15 Blocker & T-Max Tuner -
The SolarMax 40 system allows for full H-A views of the sun. This highly portable system will work on almost any telescope when attached with an adaptor plate. Adaptor plates are priced separately in accessories. It is sold with a companion T-Max tuner and BF15 blocking filter. The blocking filter is housed in a 1.25" diagonal.
The Advantage of the T-Max:Some events on the Sun,- notably active flares and coronal mass ejections (CMEs), 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. 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.
