Daystar Quantum Solar Filters

Daystar Quantum filters are heated, temperature-tuned narrowband solar filters that mount in the light path of a telescope working at a slow focal ratio. Besides H-alpha in PE and SE grades, the line covers other solar lines: Calcium II H (5Å), Calcium II K (2Å), Sodium D (0.4Å) and Helium D3 (0.3Å).

This collection also includes the Quantum power supply, front and rear plates for T, SCT and 2" connections, wedge plates and an 80mm extension tube.
