OPTOLONG

Optolong is the astronomy filters division of Yulong Optics, an optical filter design and processing company from Kunming, China. They have supplied over 700 optical organisations worldwide since 1999 and now offering directly to the public.

In our experience they listen to customer feedback and do their best to constantly improve the quality of their products. They also offer some unique products, like the L-PRO that offers strong reduction of light pollution, whilst it lets through maximum amount of the useful part of the spectrum.

They have been accused to sell copyrighted products, however that competing filter manufacturer has got copyright for those clip filters only for Germany that's why we will not sell those filters to Germany, but we can supply all their filters to any other country in the world. They were also accused by the same competitor that their filters are of "usual Chinese quality", well, we do not thing that such generalisation is correct, if you think about it, the largest portion of high end electronics are made in China, so what is now "usual Chinese quality". We don't say that you cannot find some really low quality products in China, but these certainly do not belong to that category. Our experience is that, other than few issues, we have not had many complaints about the quality of their filters, and had many happy customers during the years, so these offer a good value.
