This Prominence telescope uses multiple technologies to protect human eye during 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.

The prominence telescope uses a combination of front and rear filters to allow only monochromatic light with a wavelength of 656.28 nanometers emitted by hydrogen atoms to pass through, while blocking other light with different wavelengths. This allows the observation of quite active prominences in the H-α band.
