• Lunt Solar Systems LS100 Hydrogen-Alpha Filter - Front Mount

  The new Lunt Solar Systems LS100 Hydrogen-Alpha Filter incorporates a unique design feature which decreases chances of decontaction (breakage) and increases solar filter thermal stability, an important factor since even the slightest temperature change can cause poor h-alpha performance. Since solar prominences tend to fade into the bright background sky at 1.0 angstroms, the Lunt Systems Solar Filter's performance at <0.7 angstroms gives above average contrast and definition. To help achieve greater details than ever before, the Lunt Solar Systems H-Alpha filter can also enhanced by adding a second etalon system (sold separately under "Accessories") to reduce the bandpass of the LS100 H-Alpha to <0.5 angstroms. That's a substantial crisp detail bonus to both photographers and observers! The tighter the bandwidth, the more contrast and details on both prominences and surface features...
  
  Another addition to the Lunt Solar Systems LS100 Hydrogen-Alpha Filter is the supplied B1200 blocking filter. This allows the Lunt H-alpha filter to be attached to any refractor with less than 1200mm of focal length. The Lunt Solar Systems B1200 Blocking Filter houses an additional filter in the specialized 2" diagonal. 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 B1200 filter will provide a full disk image of the Sun with telescopes which have a maximum of 1200mm 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. Mounting adapter is sold separately.
