That's why astrophotographers must still understand how to focus the image from a telescope, track the image during long exposures, and combine and process images to maximize detail and minimize noise. Compared to the old days of film astrophotography, modern digital astronomy cameras and DSLRs are extremely sensitive and relatively easy to use, and they create images that can be easily enhanced with sophisticated processing software.īut technology is never a substitute for getting a correctly exposed image onto the camera sensor.

Thanks to continuous advances in semiconductor technology and image processing techniques, amateur astronomers now have at their disposal camera technology that rivals what was available to professional astronomers less than twenty years ago. Color Correction & Minus Violet Filters.Correctors, Focal Reducers & Flatteners.The filter corrects the displaced colour reproduction of a converted camera so that it can also be used for normal every-day photography, without having to revise every image on the computer. For the owners of astro-modified cameras we offer the Astronomik OWB filter: OWB stands for "original white balance".Images in these narrow emission lines are not naturally coloured.

With these filters you can create detailed images of faint objects even from locations with extreme light pollution and a full Moon high above in the sky. For a more in-depth introduction to astrophotography, we recommend the OIII, H-alpha and SII emission lines filters, available with full width at half maximum of 6nm or 12nm.The background suppression is significantly stronger than with the CLS, however this filter works only for gas nebulae! Star clusters and galaxies are largely filtered out. The transmission curve of this filter only allows the light of the H-beta, OIII, H-alpha and SII lines to pass through. A good choice for working in locations with really heavy light pollution is the Astronomik UHC filter.Therefore you will need the CLS-CCD filter for an astro-modified camera! Important: the simple CLS filter has no built-in IR-blocking. The filter is optimised in such a way that objects are reproduced in their natural colours. By using this filter you get a dark-sky background and can therefore use much longer exposure times to make fainter objects visible. This filter suppresses artificial light pollution and natural airglow. As a first filter, we recommend the Astronomik CLS filter.When using Astronomik UHC filters you will quickly notice the same needle-sharp stars which you are familiar with from your astronomical instrument without any filter! Another major advantage of our Astronomik UHC filter is the high optical quality of the filter glass. Transmission losses and chromatic distortions, which arise with other filters, only occur with Astronomik filters when extremely bright aperture ratios of 1:2 and more come into play. The Astronomik filters are optimized for use with telescope focal length f / ratios of f/4 to f/15. With this strong blocking of the sky background an unexpected wealth of detail becomes visible for gas nebulae and planetary nebulae.Īstronomik UHC filters’ astounding high light transmission brings better views of deep-sky-objects even to small telescopes! The high transmission of the optical glass filters means that enough light is available to allow successful visual observations with telescopes beginning at 2" (50mm) aperture. While 1.25' eyepieces are perfectly suitable for viewing the night sky, more seasoned astronomers typically lean toward the larger 2' models, allowing for larger fields of view and often higher quality optics. All annoying, scattered light from other wavelength sources, including local artificial light pollution, is reliably filtered out. Many telescopes allow use of either size barrel, so verify your telescope's individual focuser specifications prior to any purchase. Though the second window for the H-alpha-line is not intended for visual observing, it is important, if the filter is used with an electronic device. 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. You will enjoy using your Astronomik UHC filter because you will see more stars and more details in deep-sky-objects compared to using filters from all other manufacturers. The Astronomik UHC is the filter for visual observing.
