Product Details

  • Now introducing the Lunt Solar Systems LS100THa H-Alpha Telescope! Good for beginners, this a refractor-based system starts off with a 100mm precision aligned ED doublet lens with a focal length of 500mm. Inside this custom-made refractor, you'll find an internal etalon with tune adjustment which allows for a maximum of <0.75 Angstrom bandpass. You'll get a sharp, crisp ~7.3mm image through its 6mm blocking filter (sold separately), revealing excellent details on both the solar surface, limb edge, flares, and prominences. We're talking about a professional level quality solar telescope at an affordable price!

    But there's more than just a pretty view... You can achieve coarse focus adjustment with a slide tube, and then fine adjustments to focus are accomplished via the included dual-speed 2" Feathertouch focuser with 10:1 reduction. Its clamshell mount is compatible with most tripods and mounting holes are all part of the Lunt Solar Telescope System... Right down to the stylized white pearl paint with anodized black trim and included the foam-lined hard case!
