Lunt Solar 100mm H-Alpha Filter - B3400 for 2" Focusers
Lunt Solar Systems LS100 Hydrogen-Alpha Filter - Front Mount
Another addition to the Lunt Solar Systems LS100 Hydrogen-Alpha Filter is the supplied B3400 blocking filter. This allows the Lunt H-alpha filter to be attached to any refractor with less than 3400mm of focal length. The Lunt Solar Systems B3400 Blocking Filter houses an additional filter in a 2" straight through with a tiltable filter mechanism. The blocking filter is just as crucial to your safety and the system's performance as the front element of the Lunt LS100 solar package! The secondary blocking filter is based on the focal length of your telescope - because blocking filters shape the spectral output. The Lunt Solar System's B3400 filter will provide a full disk image of the Sun with telescopes which have a maximum of 3400mm of focal length. It is important to chose your Lunt h-alpha filter solar filter carefully, because using a larger blocking filter than necessary to achieve a full disk image in your telescope system may result in image "ghosts" at the edge of the field of view. Because the Lunt 100mm H-Alpha Front Mount Filter is unique, the h-alpha blocking filter is also unique. Lunt will only warranty the safety and/or performance of their solar systems when a Lunt Solar Systems blocking filter is paired with a Lunt Solar Systems Etalon system. A mounting adapter for your particular telescope is sold separately.
