DESCRIPTION:

      Enjoy rarely-seen views of the Sun's surface and rim with the Lunt Solar Systems' 60mm f/8.3 Hydrogen-Alpha Single Etalon Refractor Solar Telescope. This dedicated solar scope features a 60mm objective lens , a 500mm focal length, and an internal etalon with a <0.75 Angstrom band pass. The scope is offered here with a 6mm blocking filter in a star diagonal configuration. It fits in the Crayford-style focuser and accepts 1.25" eyepieces and accessories and should be used for visual observation only. Its dual-speed Crayford-style focuser uses a toothless friction system that allows for super-fine precision focusing without backlash. This solar scope comes without a mount or tripod, but is outfitted with a mounting base that has a 1/4"-20 threads for attaching it to most tripods or compatible mounts. For safe transportation and storage, a foam-lined hard carrying case is included.
