Lunt Solar Systems - 100mm H-Alpha Etalon

Are you ready to use the double-stack technique to reduce bandpass and get the best possible resolution and contrast from your Lunt Solar System telescope? Then check into the Lunt 100mm H-alpha Etalon. This 100mm aperture filter will reduce the bandpass of a Lunt LS-100 solar system to <0.5 - dependent slightly on the telescope. What's more, if you order this extra Etalon at the same time you purchase your LS-100, the two filters will be matched at the factory. If you already have an LS-100 and want to double-stack, please contact OPT for instructions that will ensure your current Etalon and your new Etalon match up properly.
