Antlia Hydrogen Alpha (Ha) 4.5nm EDGE 2" Filter (ANT-HA-45NM-EDGE-2)

Antlia Hydrogen Alpha (Ha) 4.5nm EDGE 2" Filter (ANT-HA-45NM-EDGE-2)Antlia H alpha EDGE narrowband filter optimizes the FWHM (full width half maximum) to 4. 5nm bandpass. The suppression of optical density (OD) 5 on unwanted wavelengths and the excellent transmittance characteristics found in the Antlia 3nm Pro series has been incorporated into the 4. 5nm EDGE narrowband filters. The result is that these filters deliver superior SNR (signal to noise ratio) and better contrast in your images. Conventional broader

lower readout noise and higher sensitivity
