Deep Sky Filters

The Astronomik H-beta filter is a narrow band emission-line filter for CCD photography. The filter lets the H-beta light of emission nebulae pass and blocks nearly the whole remainder of the spectrum where the CCD is sensitive.

The Astronomik SII-CCD filter is a narrow-band-filter for CCD photography.The filter lets the light of the ionized sulfur (SII) pass, and blocks nearly the whole remainder of the visual spectrum as well as IR, in which the CCD is sensitive.

IDAS NB Filters are designed to enhance the contrast of emission nebula, yet accommodate the filter spectral shift* when used with modern fast optical systems.

The popular CLS clip in filter now available for full frame cameras such as the 5D and 6D. A very useful light pollution/deep sky filter for SLR imaging.

L-Quad Enhance Filter is a quad bandpass light pollution suppression filter for colour cameras. It effectively
suppresses the transmission of light pollution wavelengths

The Astronomik CLS CCD is suitable under light-polluted skies for DSLR Cameras, which have been remodeled for astronomical use. The filter enhances the contrast between all deep-sky objects and the background.

Astronomik has added a new range of RGB filters to its line of World class products. The new Deep-Sky RGB filters are designed for maximum deep sky imaging performance with CCD cameras.

A new generation Venus filter that allows Amateurs to image fine detail on Venus for the first time. The latest coating technologies permit the Baader Venus Filter to transmit from 300nm to 400nm, with a peak transmission of 80%!

For all astrophotography enthusiasts, filters are one of the indispensable accessories to achieve perfect deep-sky imaging.
