List of products by brand Optolong

Optolong is China's largest manufacturer of optical filters, with unique products, such as the L-Pro, with 5 pass bands located in regions of the visible spectrum where astronomical objects emit, but prevents stray light from passing through.
Optolong Optics Co. Ltd. is a manufacturer of astronomy filters, and other types of optical filters with applications in multiple industrial sectors. Located in Kunming City in China, their more than 20 years (since 1999) of experience in optics and multilayer coating technology of optical glasses allows them to design and produce filters with a combination of really sophisticated optical windows. Currently, Optolong is the first astronomical filter brand in China, with exclusive products. The L-Pro filter, which prevents the passage of artificial stray lights, has five pass bands, located in those regions of the visible spectrum where astronomical objects emit, and has received a highly positive response among amateur astronomers and astrophotographers.Optolong also manufactures other filters such as UHC, H-Beta, O-III, H-Alpha, SII, LRGB, Night Sky H-Alpha Less
