Optolong L-Ultimate Dual Narrowband Filter - 2" rotator Solar observation possible through theThe Optolong L Ultimate dual narrowband filter is designed to drastically reduce the effect of light pollution and capture a very specific wavelength of light emitted from deep space emission and planetary nebula. Its two ultra narrow 3 nm passing bands isolate the nebulae emissions in Ha (red) as well as OIII (green blue). This effectively means local light pollution is much less significant and even imaging during a full moon is possible too as all
