Product Description


The new Lunt Solar Systems LS50 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.

Another addition to the Lunt Solar Systems LS50 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 LS50 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 blocking 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 50mm 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.

 

  • Lunt Solar Systems LS50 Hydrogen-Alpha Filter is an integrally tuned Etalon system with 50mm aperture.
  • Provides incredibly high contrast views of solar surface and edge details.
  • Lunt Solar Systems LS50 Hydrogen-Alpha Filter has an estimated bandpass of <0.7 Angstroms.
  • B3400 blocking filter included for refractors with less than 3400mm focal length with a 2" focuser.
