ANTLIA ALP-T Ha & OIII 3nm DUAL BAND FILTER coma Its low profile of onlyThe Antlia ALP T Golden H alpha and O III 3nm Dual Band filter is specifically designed for astrophotography with colour DSLR, CMOS or CCD cameras in areas with heavy light pollution. Its two ultra narrow 3nm passing bands do an incredible job at isolating nebulae emissions in H Alpha and OIII. The optical density of 4. 5 suppresses unwanted wavelengths from light pollution, moonlight and skyglow, resulting in superior signal to noise ratio and better
