This SolarMax II 60 H-Alpha Solar Viewing Filter Kit is comprised of a 60mm aperture narrowband H-a filter with the TMax tuner, and a BF-30 blocking filter. It is maximized for telescopes equal to or shorter than a 3000mm focal length. The filter increases the bandwidth from <0.5 to <0.7 ⿫ providing greater detail and sharpness of the solar features.



SolarMax II H-Alpha filters allow viewing of the active surface of the sun with 100% safety. None of the parts of this kit are stand-alone units - each component is equally crucial to the user's safety and the system's performance.



The SolarMax II 60 filter comes with the T-Max 60 Doppler Tuning Unit. The T-Max is used to de-tune the telescope's optical system. The wavelengths produced by high-velocity events such as active flares and coronal mass ejections (CME) can Doppler-shift and become invisible to an H-Alpha tuned system. The T-Max unit allows the user to de-tune the SolarMax filter slightly to make these phenomena more visible.



A Rear-Blocking Filter is also included in this kit, and it is designed for use with telescopes that have a focal length equal to or shorter than 3000mm. The BF-30 is a 1.25" right-angle diagonal, and it must be used in conjunction with the SolarMax filters.

SolarMax II 60 H-Alpha Filter
Converts telescopes with a focal length equal to or shorter than 3000 mm into a <0.7 Å solar viewing system
T-Max 60 Doppler Tuning Unit
Attached directly behind the etalon, the tuner adjusts to compensate for Doppler shifted light. By de-tuning the SolarMax filter towards the blue end of the H-Alpha line, the T-Max 60 facilitates enhanced observation and imaging of solar disk shapes, surface details, prominences, granulation, and edge activities
BF-30 Blocking Filter
Designed for use with telescopes that have a focal length equal to or shorter than 3000 mm, the BF-30 is a 1.25" straight type that must be used with a SolarMax filter
