Antlia Hydrogen Alpha (Ha) 3nm Pro Highspeed 2" Filter (ANT-HA-3NM-PRO-2-HS)

Antlia Hydrogen Alpha (Ha) 3nm Pro Highspeed 2" Filter (ANT-HA-3NM-PRO-2-HS)Antlia's SHO 3nm Pro Highspeed Filters are further optimized for high speed imaging systems by pre shifting the center wavelength. This specially optimized version will provide significantly SNR (Signal to Noise Ratio) for the fast telescopes with focal ratio between f 2. 6 and f 3. 6 than the standard 3nm Pro version. The optical light path of a telescope is cone shaped, which creates an angle, and the center wavelength of the interference filter
