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.

Designed and engineered for use by amateurs and researchers to observe the sun, Daystar Filters' 5.0Å Calcium II H-Line Quantum Filter is built with anti-reflection coated BK7 glass and highly-precise electronic tuning. H-line filters are used to study the solar atmosphere, and reveal complex temporal variations in the chromosphere.

Since much solar research is conducted remotely, there is an integrated RS-232 serial port that enables remote viewing of the filter's display and control of its tuning. Daystar recommends using the filter with imaging systems set between f15 and f/20, and runs on 12 VDC power. It comes with a 6' power cord and a set of international outlet plugs for US, EU, UK, and Australia.
