Professional 100 mm H-alpha telescope with maximum field of view for photography<\/strong><\/h2>\n\n\n\n

The Lunt LS100MT ST 100\/714 Ha B1800 All-round OTA<\/strong> is the choice for advanced solar photographers and observatories who want the widest possible H-alpha field of view without sacrificing contrast and resolution. With a 100 mm aperture, fully obstruction-free optics and a B1800 block filter, you get more room for large camera sensors and high magnifications, while fine filament structures and prominences remain in focus.<\/p>\n\n\n\n

The difference in user comfort between B1200 and B1800 is great for photographers: less vignetting, more edge stability and a significantly wider sweet spot area across the sensor.<\/p>\n\n\n\n

FPL-53 triplet optics: maximum sharpness and perfect correction<\/strong><\/h2>\n\n\n\n

Whereas the 60 mm and 80 mm models use ED doublets, the LS100MT uses a full-scale FPL-53 triplet<\/strong>. This is comparable to the build quality of high-end APOs for deep-sky astrophotography.
The result:<\/p>\n\n\n\n

    \n
  • very low chromatic aberration<\/li>\n\n\n\n
  • Pointed stars in night mode<\/li>\n\n\n\n
  • maximum resolution in H-alpha<\/li>\n<\/ul>\n\n\n\n

    For serious solar observers, this is a clearly noticeable upgrade: fine spicule fields, filament sides and active regions show more internal structure and stability.<\/p>\n\n\n\n

    B1800 block filter: optimized for large sensors and bino viewers<\/strong><\/h2>\n\n\n\n

    The B1800 block filter with 18 mm aperture gives you a wider field of view than any of the smaller filter variants. It is ideal for:<\/p>\n\n\n\n

      \n
    • large camera sensors (APS-C, IMX571, IMX183, etc.)<\/li>\n\n\n\n
    • full-disk sun photography<\/li>\n\n\n\n
    • prominence photography with larger sensors<\/li>\n\n\n\n
    • binoviewers with higher magnification<\/li>\n<\/ul>\n\n\n\n

      For photo-based setups, this is the practical high-end choice.<\/p>\n\n\n\n

      Robust R&P focuser and full All-round equipment<\/strong><\/h2>\n\n\n\n

      The 2\u2033 Rack & Pinion focuser with 1:10 micro fine adjustment carries heavy cameras and accessories with ease. The telescope comes in a sturdy transport case (78 \u00d7 33 \u00d7 23 cm), complete with sun finder, tube rings, handle and Vixen-style dovetail.
      With a transport length of 650 mm, it remains surprisingly portable for a 100 mm H-alpha telescope.<\/p>\n\n\n\n

      What we recommend (including what you can see with it)<\/strong><\/h2>\n\n\n\n

      With the Lunt LS100MT Ha B1800<\/strong> you can count on:<\/p>\n\n\n\n

        \n
      • \u2713 wide and stable field of view without vignetting on large sensors<\/li>\n\n\n\n
      • \u2713 very sharp prominences with internal structure<\/li>\n\n\n\n
      • \u2713 clear filament layers, plages and active areas<\/li>\n\n\n\n
      • \u2713 Visibly higher resolution than 60 mm and 80 mm systems<\/li>\n\n\n\n
      • \u2713 use as a high-quality 100 mm APO for moon, planets and bright deep-sky objects (in night mode)<\/li>\n\n\n\n
      • \u2713 perfect for advanced photographers, solar observatories and semi-professional use<\/li>\n<\/ul>\n\n\n\n

        The B1800 is ideal for photography-heavy setups. For purely visual use, the B1200 variant is usually sufficient, but the B1800 gives extra margin and future-proofing.<\/p>\n\n\n\n
