  • Lunt Solar Systems - 60mm H-Alpha Etalon for Double-Stacking

    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 60mm H-alpha Etalon. This 60mm aperture filter will reduce the bandpass of a Lunt LS-60 solar system to <0.5 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-60, the two filters will be matched at the factory. If you already have an LS-60 and want to double-stack, please contact OPT for instructions that will ensure your current Lunt Etalon and your new Lunt Etalon match up perfectly.

    Lunt Solar Systems creates their line of h-alpha solar telescopes and h-apha accessories in Tuscon, Arizona. 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. These are names you'll recognize, including Andrew Lunt with 20 years of optical design, Markus Ludes with his extensive knowledge of telescope design, Manny Serrano as a design engineer and Brian Stevens assembling, repairing and troubleshooting etalon systems.

    Lunt Product Number: LS-60FHA

    Customer Note: This 60mm Filter cannot be used alone for solar viewing or imaging. It only works when attached to an existing Lunt LS60 Solar System, and the proper blocking filter is used. Blocking filter is not included.

    Massive step up in my solar observing

    Excellent service from OPT and easy import to the UK. The etalon needed some rotation (as well as tuning) to find the sweet spot but now I have got it in the right place the views are amazing!!
