Astronomik Deep Sky RGB Filter Set 1.25" (M28.5)

Astronomik Deep-Sky RGB Filters

Astronomik has added a new range of RGB filters to its line of world class products. The new Deep-Sky RGB filters are designed for maximum deep sky imaging performance with CCD and CMOS cameras.

Using Astronomik Deep-Sky RGB filters will benefit your imaging and will provide you with the highest-quality data for amazing images with unsurpassed sharpness, contrast and vivid colors.

Astronomik Deep-Sky RGB Key features:

maximum transmission of up to 95%

Ultra-Sharp, pinpoint star images

High contrast

easy to process data for vivid colours in the final image

optimized spectral windows for max photon counts on the sensor

made on finest, opticaly polished glass

extremly durable, scratch resistant coating

MFR Coating technique for a wide range of focal ratios

Excellent transmision characteristics

The transmission curves of the three filters are designed to give you strong and vivid colors with a strong reinforcement of the most important emission lines. Data taken with the new Astronomik Deep-Sky RGB filters is easier to process into a beautifull final masterpiece.

During the design of the Deep-Sky RGB filters, Astronomik took a close look at the sensitivity curves of today’s popular CCD and CMOS cameras. The result was they found a way to make one set of filters for all kind of sensors ranging from KAF- and KAI-sensors, to the chips made by Sony, meaning you can do 1:1:1 ratio RGB exposures with all sensors, with only minimal tweaking necessary during processing to achieve perfect colours in your image!

Technically perfected

The transmission curve characteristics and coatings on the new Deep Sky RGB filters have been designed and engineered in such a way that no halos or reflections will be visible. Even with bright stars in the field of view, you will be able to reveal the faintest structures in nebulas or galaxies.

Like all Astronomik Filters, the new Deep-Sky RGB filters are made using an extremely durable and scratch resistant coating, deposited on the finest polished optical substrate, which is free of any striae or internal strains. All substrates are made to exactly the same thickness, so all Astronomik filters are parfocal.

Well adapted luminance filters

Additional to the Deep-Sky RGB filters, Astronomik now offers you three different Luminance filters. The different spectral window of each new Luminance filters is designed to tune your setup to get the sharpest image from any optical design and any camera, even with instruments with less-than-perfect colour correction.

Additional note for observers working under light polluted skies:

If your observing site suffers from light pollution, you should try to use Astronomik´s CLS-CCD as a replacement for the Luminance filter. The transmission curve of the CLS-CCD will give you approximately the same amount of energy in all three colour channels while blocking nearly all unwanted arifical light pollution. Customers who replaced the Lx filter with the CLS-CCD are amazed by the increased quality of their data. This small change gives you the opportunity to take much deeper images from your current observing site.
