Optolong LRGB + HSO 2 "is a package of seven two-inch astronomical filters intended for use in professional astrophotographic sets.

Each filter from the LRGB palette is characterized by a high, exceeding 95% efficiency in the maximum transmission band, and thanks to the use of a very good glass substrate and covering the surface with a full multilayer coating, the resulting image it is extremely vivid and contrasting. Moreover, the separation of the G and R filters peaks was selected in such a way as to effectively eliminate the signal coming from the spectral lines of sodium lamps, which constitute the main part of the light pollution.

The narrowband filters from the HSO palette allow you to take great photos of emission nebulae, such as the famous Pillars of Creation. Moreover, the small half-width of the Hα, S II and O III bands allows for the collection of photographic material even in such unfavorable conditions as the full moon.

All filters included in the kit are covered with a full multi-layer anti-glare coating applied using ion implantation techniques. Thanks to this, the coatings are not only perfect in terms of optics, but also very durable and scratch-resistant.

The most important features of the Optolong LRGB + HSO 2 filters set "

• high-quality LRGB and HSO filters made of glass from the renowned Schott company
• full multi-layer coating eliminating glare and protecting the surface against scratches
• designed to work with full-frame cameras
