New Optolong Filter 2-inch L-Quad Enhance Filer Professional L-Quad Enhance Filter (L-QEF)

L-Quad Enhance Filter is a quad bandpass light pollution suppression filter for colour cameras. It effectively suppresses the transmission of light pollution wavelengths, especially light pollution generated by artificial lighting (including mercury and sodium lamps), as well as the effects of natural skylight-induced effects on the shot, thus effectively enhancing the contrast and details of the celestial bodies, and making the objects more distinct and stereoscopic. This filter provides better ▲Better suppression of starbursts; Higher contrast and more details of the celestial bodies; Better colour saturation; Better signal-to-noise ratio (SNR); ▲Near IR cut-off to 1000nm, reducing the effects of IR noise; ▲L-QEF has more than 90% transmittance of the nebula emission lines at H-Beta/OIII/H-Alpha/SII, with cut-off depth from OD2 to OD4, thus providing a significant increase in resistance to light pollution. L-QEF is good for night sky from Bortel 1 to Bortel 7 levels; (Bortel 8, Bortel L- Quad Enhance Filter Spectrum: Based on the characteristics of celestial bodies’ emission lines and light pollution emission lines, L-Quad Enhance filter effectively reduces the impact of light pollution and suppresses the background light of astronomical objects, thus effectively enhancing the contrast and details of the celestial bodies. Using L-QEF filter can help you save a lot of time during the shooting process, yet obtaining incredible results.
