Baader Highspeed Narrowband Filters

Baader Highspeed narrowband filters are CMOS-optimized H-alpha, O-III and S-II filters designed for very fast optics at f/2 and f/3, such as RASA and Hyperstar systems. Their passband is matched to the steep light cone of these systems, so the emission line still reaches the sensor at full strength.

Choose between Highspeed (6.5nm) and Ultra-Highspeed (3.5nm H-alpha, 4nm O-III and S-II) versions, sold individually or as complete H-alpha/O-III/S-II sets.
