Internal Double Stack - Small Format for LS80MT & LS100MT<\/h2>\n

\nVisit Internal Double Stack Small Format<\/strong> is an internal module for telescopes. LS80MT<\/strong> and LS100MT<\/strong>. It allows you to transform your standard configuration into a system. double internal standard<\/strong>, significantly enhancing contrast in H-alpha observation.\n<\/p>\n

\n

Internal Double Stack principle<\/h3>\n

\nAdding a second standard reduces the system's effective bandwidth, enabling :\n<\/p>\n

    \n
  • Significantly enhanced contrast on the solar surface<\/li>\n
  • Better filament definition<\/li>\n
  • More pronounced active ranges<\/li>\n
  • A finer chromospheric texture<\/li>\n<\/ul>\n

    \nUnlike front-end modules, this version internal<\/strong> maintains the mechanical balance of the tube and protects the optical system in a compact configuration.\n<\/p>\n

    \n

    Small Format - optimized use<\/h3>\n
      \n
    • Optimized for visual observation<\/li>\n
    • Ideal for small and medium format cameras<\/li>\n
    • Compact, integrated solution<\/li>\n<\/ul>\n

      \nThe Small Format version is particularly suited to users wishing to maximize contrast without aiming for very large sensors.\n<\/p>\n

      \n

      Compatibility<\/h3>\n
        \n
      • LS80MT<\/strong><\/li>\n
      • LS100MT<\/strong><\/li>\n<\/ul>\n

        \nThe module integrates directly into the compatible optical system, without the need for an external front-end.\n<\/p>\n
