Astromania Telescope LRGB 2 Inch Filter Set

L - luminance filter
For the monochrome channel, The luminance filter passes the entire visible light spectrum but blocks near UV and IR light - so this filter collects all the useful object information.


RGB - each filter has a special task
- Red filter
- Green filter
- Blue filter
These three letters stand for the three different RGB colour filters from which you finally create your colour photograph. The colours that we perceive consist of the three primary colours - red, green and blue. Combined, these give all the colours that we can see. Our eyes too mix all the colours of our world from internal RGB receptors (or filters).

Combination effect

This LRGB filter set allows you to use your monochrome CCD camera to put together high resolution colour images.
Combining separate images taken through these filters produces finer resolution and amazing color. Red, blue, and green filters plus the haze-eliminating Luminance filter give you stunning results.

Glass filters

The LRGB set features dichroic glass filters designed for maximum transmission. The color filters have an IR-blocking coating, and all filters are parfocal to eliminate the need for refocusing between exposure sets.
Attaches easily to any 2" astrophotography accessory. The anodized aluminum cell threads into the nosepiece of an astrophotography camera or filter wheel.

Colour image

The individual images from each of these four filters are combined to produce a higher resolution colour image. That is because each colour channel uses all the pixels on your camera, a very different story from colour cameras.
This set is best used in conjunction with a filter wheel, which allows you to easily change to a new filter after each set of exposures by simply rotating the filter wheel. The result is that, image by image, the components of the final, composite, colour astronomy image are exposed.
