SAFETY FIRST: Observing the Sun without the proper protection may result in serious personal injury, including permanent eye damage and blindness, and/or damage to equipment. Never point an optic at the sun without an approved solar filter on the front of the optic. For direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder, ensure your filter is ISO 12312-2 (also written as ISO 12312-2:2015) certified. Never use photographic neutral density filters for direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder.

Lunt Solar Systems LS60THa overview

Enjoy rarely-seen views of the Sun's surface and rim with the Lunt Solar Systems' 60mm f/8.3 Hydrogen-Alpha Double-Stacked 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 as a double-stacked system with an internal etalon and removable external front etalon that reduces the bandpass to <0.5 Angstrom for increased contrast and enhanced views of the seething caldron of the surface and rim activity. It comes with a 6mm blocking filter in a star diagonal configuration that 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, two foam-lined hard carrying cases are included, one for the OTA and a smaller one for the front filter.
