1, Ultrahigh quality, pinhole free BK 7 Glas-Solarfilters ND 4.0 ( photo-visuel usable). This filters are polished partly 10~ 50 times better than cheap glasfilters.

The cell by this filters is made for your specific Telescope.
- clear aperture 152 mm $ 595
- clear aperture 180 mm $ 795

we recomment such super high quality filters for mainly real high quality telescopes ( Maks, Apos, high end Achromats) , because such telescopes can take out the most of them.

2, Solarprism = real Herschelwedge with a set of extrem high quality photovisuel neutral densitiy filters from famous Schneider/Kreuznach manufactor in germany. The sunbeam is blocked at side by metalcovers. We know some dealers or manufactors due not offer them because the are not 100% safe. But they are not 100% safe only ,if you have zero experience with even beginner telescopes. They have been manufactored and sold by famous Companys like Zeiss, Baader Planetarium and they cannot be betted in terms of resolution, contrast and quality, and because they are very safe if you use them in a normal way. They are unsafe only if you go under your telescope and you looking into the outbeamed sun, which is about the same as if you take your telescope and observe the sun without any filter. No normal amateur will do it.

- 1.25" Herschelwedge with Photo-visuel filterset $ 240
- 2" Herschelwedge with Photo-visuel filterset $ 380

shipping cost on request when we know oyur country.
