Description

The SolarMax 40 system allows for full H-A views of the sun. This Telescope includes the T-Max tuner and 5 mm blocking filter. The blocking filter is housed ina 1.25" diagonal. This combination allows for a full disc image

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.

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.

MaxScope 40 was reviewed in Sky & Telescope August 2002 issue and has been awarded a "Hot Product for 2002" award by the magazine

The use of a special H-Alpha doublet lens designed by Dick Buchroeder (including optimised anti-ghosting) and superb multi-layer anti reflection coatings on all surfaces delivers diffraction limited, extremely high contrast performance.
