Vendo il filtro Astronomik UHC 2 inch M48. - Applicazione filtro Visuale*~Fotografico - Tipo di filtro Broadband*~Inquinamento luminoso*~UHC. - Filter size 2 inch (50,8mm).
The Astronomik UHC (Ultra High Contrast) filter allows the transmission of nearly 100% of the radiation from both O-III and the H beta lines.
Suitability •Visual observation (dark skies):
Very good, for telescopes of all apertures and high exit pupil •Visual observation (urban skies):
Very good, for telescops from 100 mm aperture
•Film photography: Reasonable, but very long exposure time •CCD photography: Good, when used with an additional IR-block-filter
•DSLR photography (original): Good, colour balance shifted but contrast enhanced
•DSLR photography (astro modified): Very good, colour balance is near perfect
•DSLR photography (MC modified): Good, when used with an additional IR-block-filter
•Webcam / Video (Planets): Unsuitable
•Webcam / Video (Deep Sky): Good, if light pollution is a big problem Technical Data
