Filtres bibandes Optolong

Les filtres bibandes Optolong isolent deux raies d'émission ou plus en même temps, ce qui permet aux caméras couleur de photographier les nébuleuses malgré une forte pollution lumineuse ou la Lune. La collection comprend les Ha/OIII L-Para 10nm, L-Extreme 7nm et L-Ultimate 3nm, le L-Synergy 7nm SII/OIII, et les multibandes L-Enhance et L-Quad Enhance.

Une bande plus étroite donne plus de contraste en ville mais demande des poses plus longues. Les ensembles Dual-Combo couvrent Ha, OIII et SII.
