The Optolong L-Pro (L-Professional) is a multi-bandpass filter designed for astrophotography, specifically to suppress light pollution. It effectively blocks emissions from mercury vapor lamps, sodium vapor lights, and skyglow, while enhancing major nebula emissions. This filter offers excellent color balance and allows for imaging objects with wide emission spectra, such as galaxies, with minimal color cast.
Features:
* Multi-bandpass light pollution filter for astrophotography
* Precise and sharp roll-off at light pollutant emission lines
* Very high transmission (~90%) at major nebula emission lines (OIII, H-beta, NII, H-alpha, SII)
* Multi-layers anti-reflection coating
* CNC machined filter cell made from aerospace grade aluminium with a black anodised finish to extinguish reflections
