Optolong L-eNhance Light Pollution Dual-Bandpass Imaging Clip Filter for Canon EOS APS-C
Optolong L-eNhance Dual Band Pass Imaging
Clip-Filter for Canon EOS APS-C
The Optolong L-eNhance filter was designed especially for color CMOS/CCD and DSLR cameras. The special characteristics of the L-eNhance allows amateur astronomers to get great results when imaging, even in urban skies degraded by heavy light-pollution, with just one filter!
This L-eNhance clip-filter is designed for Canon EOS APS-C format cameras. See below for a complete list of compatible cameras.
The L-eNhance optimized dual-band filter significantly blocks light pollution while allowing up to 90% transmission of H-Alpha, H-Beta and Oxygen III emission lines.
As you can see from the specifications and transmission curve chart, Optolong designed this dual-band pass filter to retain the prominent colors of nebulae in RGB while blocking out most wavelengths of light pollution. This multi-purpose imaging light pollution filter even allows for SHO Hubble palette simulation with a few tweaks in your image processing software.
