Coronado Tmax Doppler Tuner Product Info

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 Coronado T-Max Doppler Tuner allows the user to de-tune the Solarmax slightly to bring such phenomena into better visibility.

All SolarMax series filters from 2002 to the present day, and most SolarMax 40 Filters, have come with a T-max as standard equipment. Contrary to a widely held perception the Coronado T-Max Tuner does not act as a tuning device but actually de-tunes the filters towards the Blue end of the H-Alpha line. It accomplishes this by changing the angle at which the light passes though the Etalon. Situated directly behind the SolarMax unit it is comprised of two black plates, set screws, and a knurled knob that, when turned, causes the two plates to separate. One remains parallel to the telescopes objective cell while the other creates an angle between the etalon and the objective cell. This angle is less than .7 degree. Any more of an angle and the filter will be removed completely off band. Within the Coronado T-Max Tuner range of movement there will be the optimal view, further tilting, in either direction, than the CoronadoT-Max allows will not result in a better view.

If your SolarMax or AS1 series filter was delivered before the Coronado T-Max Tuner was available you can easily add this accessory by calling Coronado with the serial number of your filter. Helios I, ASM, and SMN series filters will not accept the Coronado T-Max Tuner.

WARNING! The only object in the sky that can cause irreversible damage to the observer is the Sun. Consequently, the potential user of an instrument for Solar observation should take every precaution that it is safe before attempting to use it - not just the first time, but EVERY time. DO NOT USE any instrument or product for which safety data and specifications accepted by eye safety organizations is not available. All Coronado products exceed these safety specifications. Do not attempt to disassemble any Coronado product; doing so will void your warranty and may compromise your safety.
