Lunt Solar 60mm H-Alpha Filter - B1800 for 1.25" Focusers
Lunt Solar Systems LS60 Hydrogen-Alpha Filter - Front Mount
Another addition to the Lunt Solar Systems LS60 Hydrogen-Alpha Filter is the supplied B1800 blocking filter. This allows the Lunt H-alpha filter to be attached to any refractor with less than 1800mm of focal length. The Lunt Solar Systems B1800 Blocking Filter houses an additional filter in a 1.25" diagonal. The blocking filter is just as crucial to your safety and the system's performance as the front element of the Lunt LS60 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 B1800 blocking filter will provide a full disk image of the Sun with telescopes which have a maximum of 1800mm 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 60mm 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. Mounting adapter is sold separately.
