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 bandpass. The scope is offered here with a 12mm blocking filter in a star diagonal configuration. It fits in the Feather Touch rack-and-pinion focuser and accepts 1.25" eyepieces and accessories for visual observation with a wide field of view, or imaging. Its rack-and-pinion Feather-Touch focuser features a dual-speed design with a 10:1 fine-focus for precision focusing. Rack-and-pinion focusers are generally better for handling heavier loads, such as larger imaging systems. 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.
