The transmission curves of the Astronomik RGB filters are optimised for the CCD- astronomy: With these filter-set, we finally can offer filters that make colour proof pictures of all objects possible. Continuum radiators like stars and galaxies as well as objects that shine only in single lines (e.g. planetary nebulas), are reproduced in their true colours. Because of the design of the band pass of the filters, the colour sensitivity of the human eye is optimal reproduced. You get CCD- pictures, that show the object optimal in his colours, just as if you would see it, if your eye would be sensitive enough.
Astronomik RGB TYP II
The Astronomik Type II filter will permit colour pictures without an extra IR- cutoff filter, because each of the three filter will be blocked near to the infrared (~1150nm). All three filter have the same thickness, so that colour images without focussing between the singular pictures will be possible. They are designed to work with nearly all CCD sensors available on the market. With these sensors you get pictures with a very good color balance.
Astro-optimized transmission curves for images without color-shifts.
Each filter blocks the IR, no additional filter necessary.
Correct images as well for very red as for deep blue objects because of reproduction of the eye´s sensitivity.
Transmission of nearly 100%.
Same optical thickness of all filters.
Insensitive to high humidity, scratches and aging.
Glass substrate of very high quality: You get the sharpest images your scope can provide.
Normaly the RGB filters are sold as a 4piece filter set: The three color
filters plus an IR-Cuttoff filter or an L-Filter (UV & IR-Cuttoff) or an MC-coated piece of glas with the same thickness. Single filters are also available upon request.
Please, ask for availability before placing your order. Thank you in advance.
