PT pressure tuner: Fine-tuning on the Etalon filter is provided via an air pressure system. A small change to air pressure within a pressure chamber inside the telescope changes the refractive index of the air, resulting in precise yet effortless adjustment to the H-alpha spectral line. The pressure tuner guarantees a uniform image with no central obstructions and a long-lasting wear-resistant etalon.
The B3400 blocking filter is very well suited to solar photography using cameras with very large sensor chips and can also be used for visual solar observation. The blocking filter is built into the focuser, not in the deflection optics as in many other solar telescopes; making this telescope ideally suited to solar photography.
