A tri-band light pollution filter designed for astrophotography
L-eNhance provides an economical and practical light pollution filter for amateurs. It is a dual-band pass filter which has been designed for DSLR, colour CMOS and CCD cameras. The convenience and cost effectiveness of this filter allows astrophotographers to image a rich selection of astronomical images, even in bright, heavily light-polluted areas.
It effectively isolates the H-alpha, H-beta, and Oxygen iii nebula emission lines and achieves a maximum transmission of up to 90-percent. The performance of this filter delivers images that superbly control the impact from light polluted skies.
