More about the product

The transmission properties of the L-RGB Typ 2c filters are optimized for CCD astrophotography. The set allows to take images in correct colour for all types of objects. Where other brands make strange compromises, we do the best colour reproduction possible. Both stars as well as objects that emit only in spectral lines, are reproduced in their true colors. You get CCD images with perfect colors, as if the objects where bright enough to be seen with photopic vision. This feature is the main difference between Astronomik filters an those of other manufacturers.

The following aspects have been most important for the design of our filterset:
- simple image processing for the user
- highest transmission (nearly 100%) for short exposure times
- adjusted transmissions of the individual filters for optimal colour reproduction
- the use of industry standards

Astronomik doesn't stop thinking at the step of taking the picture. More important a tool should be given to the astrophotographers that offers a simple and elegant editing process. To maintain the colour, we calculated our filterset for the sRGB color space, that is used as an industry standard from most manufacturers of monitors, printers and imaging software. As a user you do not need to spend time to learn about colourimetry and colour spaces. We have solved the special problems of astrophotography for you.

Due to the high-precision machining of the carrier substrate, our filters are parfocal with wedge errors below all usual margins. In order not to be the bottleneck in a high-quality optical system Astronomik filters are of course diffraction limited. Issues concerning focal distances as well as the exact location of the images of each colour image are not a problem at all!

Main use

The L-RGB filter set divides the spectrum into its components red, green, blue and luminance. Thus colour separation can be achieved with pure b/w CCD sensors. The separation corresponds to the colour sensitivity of the human eye according to DIN 5032. By using the sRGB color space it is possible to maintain the color of the image throughout the entire image processing and output. With an Astronomik L-RGB filter set and your camera you create ideal raw material for imageprocessing in the sRGB color space.

Other uses

In combination with the Astronomik line filters your images will show interesting details of astronomical objects. For example, the red image can be enhanced by H-alpha or the green image by OIII.
For planetary observation and photography the color filters are gladly "misused".

Pros

Skywatcher 150/1200 refraktorral, illetve asi 290mc kamerával használva jelentős javulás látható a képeken, a nélküle készültek után. A képek élesebbek, részletgazdagabbak. Ajánlom.
