Light pollution is an increasing problem for amateur astrophotographers. Narrowband filters with monochrome cameras can be a weapon against light pollution, but there are times when narrowband may not be desirable to use.
Optolong’s L-eNhance filter provides an economical and practical solution for amateurs. It is a dual-band pass filter which has been designed for DSLR (digital SLR), color CMOS and CCD cameras. The convenience and cost effectiveness of this filter allows amateurs to image a rich selection of astronomical images, even in bright, heavily light-polluted areas.
Optolong’s L-eNhance filter effectively isolates the H-Alpha, H-Beta, and Oxygen III nebula emission lines and achieves a maximum transmission of around 90%. The performance of this filter delivers images that superbly control the impact from light polluted skies.
