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.

  • 1Description

Lunt Solar Systems' Solar Filter Kit gives users an objective lens hydrogen-alpha filter and a 12mm blocking eyepiece filter for observing the Sun's surface and edge. The Ha filter attaches to the front objective of a user-supplied 100mm refractor telescope to provide unobstructed <0.70 Angstrom filtration. It mounts to the front of the optical tube assembly (OTA) using a telescope-specific adapter that is sold separately. This filter must be used with the eyepiece blocking filter, and another HA filter may be threaded on it to double-stack for a <0.5 Angstrom bandpass. It comes with an aluminum foam-lined hard carrying case for safe and secure transportation and storage. The 12mm aperture blocking eyepiece filter is recommended for use on optical tube assemblies (OTAs) with a focal length of up to 1200mm for visual observation or 600mm for astro-imaging. The star diagonal viewing configuration filter fits into 2" focusers, and accepts any user-supplied 1.25" eyepieces and accessories.
