Omegon Pro 2″ LRGB filter set
If you want to get the most out of your telescope and capture images with natural, faithfully reproduced colours, the Omegon Pro 2″ LRGB filter set is exactly what you are looking for. The combination of four filters - Luminance, Red, Green and Blue - allows you to compose full-colour deep-sky images using the LRGB composite technique, which is today the standard in amateur and semi-professional astrophotography. Omegon's Pro series filters are designed to meet the demands of technically experienced observers who refuse to compromise on optical quality or mechanical precision.
Precision construction for demanding conditions
The filter bodies are machined from precision-milled aluminium, which ensures low weight while maintaining high rigidity and resistance to temperature fluctuations - a critical factor during night-time observing sessions. The standard 2″ thread guarantees compatibility with the vast majority of astro cameras, filter wheels and focuser drawtube adapters of this diameter. The filter glass is precisely centred within the frame, so changing filters does not cause any significant shift in the focal plane or image distortion.
Applications in deep-sky imaging
The LRGB filter set is primarily used for photographic imaging of deep-sky objects: galaxies, open and globular star clusters, or emission nebulae captured in continuum light. The luminance filter transmits a broad range of visible light and serves as the foundation for detail and sharpness in the final image, while the R, G and B colour channels add natural colour information. The resulting LRGB composite delivers a significantly better signal-to-noise ratio compared to a purely colour exposure with a single RGB filter or a colour camera without filters. The filters can also be used for visual observation - the luminance filter in particular reduces the impact of light pollution and improves contrast when viewing faint objects from suburban locations.
Who is this filter set for?
The Omegon Pro LRGB 2″ filter set is ideal for astrophotographers working with monochrome CCD or CMOS cameras who want to achieve full-colour results with maximum control over each individual colour channel. It is equally well suited to users with a telescope on a permanent mount with an autoguiding system and to owners of compact apochromatic refractors or fast Newtonians with a short focal length. Thanks to the standard 2″ thread, integration into existing equipment - whether a manual or motorised filter wheel - is completely straightforward.
Omegon Pro series - quality you can rely on
Omegon is a brand with a long tradition in astronomical optics and accessories, having built a solid reputation through careful material selection and an emphasis on manufacturing precision. The Pro series represents the top of the brand's portfolio - these filters are intended for those who take astronomy seriously and expect reliable, repeatable performance night after night. Omegon also offers a wide ecosystem of compatible accessories, so the LRGB filter set can serve as a natural foundation for gradually expanding your setup with narrowband filters or specialised filters for Ha, OIII and SII emission lines.
