Antlia Oxygen III (OIII) 4.5nm EDGE 2" Filter (ANT-OIII-45NM-EDGE-2)

Antlia Oxygen III (OIII) 4.5nm EDGE 2" Filter (ANT-OIII-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

Due to the combination of the narrow bandwidth of 12nm and the high transmission of typically 96% the filter gives you an contrast boost

so you can use your smartphone confidently to scan the skies

Setup is quick and easy compared to a full-height tripod

This becomes especially useful with ultra low focal plane (visual Newtonian) telescopes
