Astronomik filters are a special development from
the Astro- Shop and the company Gerd Neumann jr. . You have with these
filters for the first time high- quality and still well payable interference
filters for CCD- astronomy and visual observation. Astronomik filters are
produced by a new type of method: The transmissions curves are being kept
to with mathematical precision. Real transmissions up to 99,8 % are possible.
Astronomik filters are not comparable with the known filters from Japan
or from USA. The different coats are completely sealed and insensitive
to moisture. They do not change within the years, but keep their transmission
characteristics almost for ever. The coats are so hard, that is it not
possible to scratch them by mistake. You would have to wanton with sandpaper
the filters, to get little scratches. Due to these outstanding characteristics
of the Astronomik filters, we give a 5 year guarantee.
The filters are produced in Europe, not in the
Far-East. The filters are manufactured to very high quality standards but
are still sold for a very fair and stable price. All filters are available
with the diameters 1,25" (thread M28,5x0,5) and 2" (thread M48x0,75). Each
filter will be send in a useful dust protection- case and with a printout
of the transmission curve.
