The PT pressure tuner allows for precise adjustment of the Etalon filter using an air pressure system. By making small changes to the air pressure inside a chamber within the telescope, the refractive index of the air is altered, enabling effortless and accurate tuning to the H-alpha spectral line. This ensures a uniform image with no central obstructions and provides a durable, long-lasting etalon.
