Omegon Filters 1.25'', L- RGB CCD filter set

Product description:

LRGB filter set - for astrophotography using monochrome CCD cameras

Four filters for a colour image - The LRGB filter set is used to photograph the sky in colour using a monochrome chip camera. Monochrome CCD cameras used for astrophotography provide a bright image of deep sky objects at very high resolution as all the pixels on the chip work together to produce the image. However, the resolution is minimized with cameras using colour CCD chips, as about ⅓ of the pixels have colour filters.

Only an LRGB filter set with a monochrome camera makes use of the entire chip and can hence generate a high-resolution colour image.

L - the luminance filter

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

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).

The four images from LRGB channels are combined in the image processing procedure and basically create the final colour photograph.

Tip: Using the Omegon Filter Wheel with the LRGB filter set for your astrophotography lets you change filters in just seconds.

The advantages in a nutshell:

• LRGB filter set for colour photography with CCD monochrome cameras
• full chip resolution via four different external filters
• durable - scratch-resistant coating
• neutral colours for deep sky objects and planets
