Optolong L-Pro filter 2" The L-Pro is a multi-bandpass broadband light-pollution filter that keeps natural colour balance. It suppresses the main artificial lines (Na 589 nm, Hg 435 and 578 nm) while staying highly transparent at H-beta, OIII, H-alpha, NII and SII, suiting galaxies, reflection nebulae and star clusters as well as visual use.
