Solar 50mm 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 50mm H-alpha Etalon. This 50mm aperture filter will reduce the bandpass of a Lunt LS-50 solar system to <0.55 angstroms - dependent slightly on the telescope. What's more, 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.

They have have put together a group of experienced solar enthusiasts who are looking forward to energizing the hobby with a continued commitment to advancing technologies, pride in quality, and the highest level of customer care.

Please Note: This 50mm Filter cannot be used alone for solar viewing or imaging. It only works when attached to an existing Lunt LS50 Solar System, and the proper blocking filter is used. Blocking filter is not included.
