The Astronomik UHC-E filter is our budget filter for deep-sky observation of emission nebulae and comets under light polluted skies. Itís particularly suitable for small íscopes. The UHC-E Filter increases contrast of emission nebulae and comets and blocks the light of typical streetlights as well as airglow. It is best suited for telescopes up to 5" / 125mm.
Main useThe Astronomik UHC-E filter provides a FWHM of 45nm and blocks the light of typical streetlights (e.g. sodium and mercury vapour) as well as airglow. Thus it increases contrast between your target and the night sky. The contrast enhancement is less than that of the Astronomik UHC filter, but at the same time the transmitted amount of starlight is greater. It's therefore better suited to smaller telescopes. As the UHC-E filter passes a spectral line of Carbon (due to the higher FWHM) it opens up the possibility of comet observation.
Other usesObservation of Jupiterís clouds.Easier resolution of Double Stars.Photography under light-polluted skies with DSLRs and other cameras.
AlternativesIf you use a telescope with an aperture larger than 5", we suggest the use of our standard UHC-filter because of its greater contrast enhancement capabilities. If you use a telescope larger than 8", you can try our OIII filter for even better results when observing specific nebulae.
SuitabilityVisual observation (dark skies): Reasonable, an UHC filter is more suitableVisual observation (urban skies): Good, for telescopes up to 125 mm aperture and medium exit pupilFilm photography: Good, but very long exposure timesCCD photography: Good, when used with an additional IR-block-filterDSLR photography (original): Good, colour balance is near perfectDSLR photography (astro modified): Good, colour balance is near perfectDSLR photography (MC modified): Good, when used with an additional IR-block-filterWebcam / Video (Planets): UnsuitableWebcam / Video (Deep Sky): Very good, if light pollution is a big problem
