The largest H-alpha field of view in the LS100 series<\/strong><\/h2>\n\n\n\n

The Lunt LS100MT Ha B3400<\/strong> is the most complete version of the 100 mm models. The large B3400 block filter<\/strong> gives you the widest field of view within the MT series. You notice this especially when shooting with larger cameras or when you want to capture the entire solar disk with a lot of detail. For advanced solar photographers, this is the version with the most freedom and the least restrictions.<\/p>\n\n\n\n

The 100 mm aperture delivers visibly higher sharpness than 60 mm or 80 mm models. This means that fine structures such as thin filament edges, small prominences and details in active areas become more visible.<\/p>\n\n\n\n

FeatherTouch focuser: maximum stability!<\/strong><\/h2>\n\n\n\n

This version has an original Starlight Instruments FeatherTouch Focuser<\/strong>. This is one of the most precise and reliable focusers available.
In practice, this means:<\/p>\n\n\n\n

    \n
  • Smooth focusing, even with heavy cameras<\/li>\n\n\n\n
  • no shifting or backlash<\/li>\n\n\n\n
  • precise control thanks to the 1:10 micro fine adjustment<\/li>\n<\/ul>\n\n\n\n

    For H-alpha photography, where sharpness down to the millimeter counts, this is a big advantage.<\/p>\n\n\n\n

    \n
    \"Lunt<\/figure>\n<\/div>\n<\/div>\n\n\n\n

    Why choose the B3400 version?<\/strong><\/h2>\n\n\n\n

    The B3400 is especially suitable for:<\/p>\n\n\n\n

      \n
    • larger camera sensors<\/li>\n\n\n\n
    • full-disk photography with great detail<\/li>\n\n\n\n
    • users who want maximum freedom in image frame<\/li>\n\n\n\n
    • observatories or demanding photographers<\/li>\n<\/ul>\n\n\n\n

      It is the most future-proof variant: you can use almost any camera without problems with light transmission or image vignetting.<\/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 B3400<\/strong> you can count on:<\/p>\n\n\n\n

        \n
      • stable, clear H-alpha image with lots of detail<\/li>\n\n\n\n
      • full solar disk and prominences in one shot<\/li>\n\n\n\n
      • sharp observations of filaments, spicule fields and active regions<\/li>\n\n\n\n
      • photography without limitations by sensor size<\/li>\n\n\n\n
      • Use as a high-quality APO in night observation (moon, planets, bright nebulae)<\/li>\n\n\n\n
      • suitable for advanced users and observatories who want maximum quality<\/li>\n<\/ul>\n\n\n\n

        For beginners, this model is too advanced; this is a tool for users who know exactly what they want to achieve with H-alpha.<\/p>\n\n\n\n
