The Optolong L-Pro Filter\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe Optolong L-Pro (L-Professional) filter is designed to improve the visibility of many deep-sky objects. It selectively reduces the transmission of light pollution wavelengths, particularly those from artificial lighting (mercury vapor lamps, high and low-pressure sodium lamps) and unwanted natural light due to neutral oxygen emission in the atmosphere (\"skyglow\"). At the same time, it remains highly transparent to the main emission lines of nebulae: OIII (496 nm and 500 nm), H-beta (486 nm), NII (654 nm and 658 nm), H-alpha (656 nm), and SII (672 nm). For this reason, it is suitable for increasing contrast and detail, both for visual observation and photography, in peri-urban areas with strong light pollution.\u003c\/p\u003e\n\n\u003cp\u003eUnlike other light pollution filters such as UHC and CLS, the L-Pro is a multiband filter that offers better color balance thanks to transmission bands that are as wide as possible. The balanced transmission allows you to photograph broadband emission objects, such as galaxies, reflection nebulae, and globular clusters, with minimal color casting. The L-Pro is the best choice for attenuating light pollution.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eMain Use and Performance\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eSuitable for visual observation and astrophotography. The L-Pro filter attenuates the light of continuous-spectrum objects very little, so it is very effective against light pollution when imaging galaxies, reflection nebulae, and globular clusters; the same applies to the visual observation of stars. On its own, it also blocks infrared, so it can be used safely for luminance (\"L\") imaging with CCD cameras.\u003c\/p\u003e\n\n\u003cp\u003eLight pollution filters do not eliminate the effects of light pollution and do not increase the brightness of objects: in most cases, they increase the contrast between the nebula and the sky background without making the nebula itself brighter.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWARNING:\u003c\/strong\u003e Optolong filters are not designed for solar observation.
