This system is equipped with the B3400 blocking filter, making it suitable for use with telescopes that have a focal length of up to 3060mm. The blocking filter is housed in a straight extension tube designed for a 2" focuser, which includes fittings for both 2" and 1.25" eyepieces. For those seeking even narrower bandwidth and higher contrast, an additional Double-Stack etalon can be added to reduce the bandwidth to less than 0.55 Angstrom.
