DOUBLE STACK PERFORMANCE FROM A SINGLE ETALON !!
The HELIOSTAR-76Ha uses multiple technologies to protect the human eye during solar observation, including an infrared thermal ray reflection film, a special filter to block heat, and a filter to block UV light from entering, blocking stray light that affects observation. It uses a combination of front and rear filters to allow only monochromatic light with a wavelength of 656.28 nanometres emitted by hydrogen atoms to pass through, whilst blocking other light of different wavelengths. This allows the observation of quite active prominences in the H-Alpha band.
Sky-Watcher’s etalon technology allows the Heliostar-76Ha to achieve a 0.5A bandpass without the costly expense and complexity of a second etalon to achieve the same performance. This allows the observer to obtain detailed images of the solar disk right out of the box without any further expense.
The HELIOSTAR-76Ha conforms to and meets the transmission requirements of ISO 12312-2:2015 (Filters for the direct observation of the Sun). Always use in accordance with the instructions and exercise the utmost of caution when viewing the Sun.
