Coronado SolarMax Filter 40 Set
Coronado SolarMax 40 H-Alpha System Filter with BF-5 and T-Max Tuner - The SolarMax 40 is a 40mm <0.7A, AS1-Series thermally stable H-Alpha filter. This package includes a BF5 (5mm 1.25" right angle diagonal blocking filter) and a T-Max tuner. Adapter plates available separately. This package is optimized for scopes with a focal length of not more than 500mm.

The SolarMax 40 was designed specifically for use on short fast refractors under 1000mm focal length. Though small in size the 40mm filter is large enough to resolve fine detail in surface structure and on the limb of the Sun. The front mounted SolarMax and rear blocking filter. Almost all telescopes will require an adaptor plate in order to attach the SolarMax, these are available from Coronado or through your dealer.

The SolarMax includes a T-Max de-tuning device. 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. The T-Max allows the user to de-tune the SolarMax slightly to bring such phenomena into better visibility.
