Lunt Solar Systems Solar telescope ST 100/714 LS100MT Ha B3400 Allround OTA (83369)

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.

The B3400 blocking filter is especially well-suited for solar photography with cameras that have very large sensor chips, and it can also be used for visual solar observation. Unlike many other solar telescopes, the blocking filter is built directly into the focuser rather than the deflection optics, making this telescope ideal for advanced solar imaging.
