Use the double-stack technique to reduce bandpass and get the best possible resolution and contrast from your Lunt Solar System telescope. The Lunt 50mm H-alpha Etalon 50mm aperture filter will reduce the bandpass of a Lunt LS-50 solar system to <0.55 angstroms - dependent slightly on the telescope. If you order this extra Lunt Etalon at the same time you purchase your Lunt Solar Systems LS-50, the two filters will be matched at the factory. Please know that this Etalon stack MUST be used with the appropriate Blocking Filter! Blocking Filter is NOT included!
