Product Details


  • Enjoy everything the Sun has to offer — prominences, surface granulation, active regions, filaments and more seem to leap from our closest star, all captured in the stellar quality performance you expect from a Lunt Telescope.

    When the Sun sets, simply remove your hydrogen alpha module, replace your focuser, and let the nighttime in!

    The Lunt 100 mm packs a powerful triplet ED APO lens (FPL53 glass) that will guide you across the Milky Way in stunning detail. Now you have a top-of-the-line, extra-low dispersion (ED) nighttime telescope to view planets, stars, the Moon and anything else in between!

    2″ Feather Touch Focuser

    The Starlight Feather Touch Focusers have been redesigned and is even better than the original! All running parts are now hardened stainless steel on hardened stainless steel. This greatly improves the smoothness, wear characteristics and its robustness. This new design will virtually not wear out and moves with even greater smoothness and precision than the original model. It is still an absolute must for CCD imaging and astro-photography, in addition to making visual use a joy.
