Astronomik Deep-Sky RGB Filterset 50 x 50mm², unmounted, 3 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 cameras.
Using Astronomik Deep-Sky RGB filters will benefit your imaging and 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 colors in the final image
• Optimized spectral windows for maximum photon counts on the sensor
• Made from the finest, optically polished glass
• Extremely durable, scratch-resistant coating
• MFR coating technique for a wide range of focal ratios

The new Astronomik Deep-Sky RGB filters are the result of long and detailed research and development. These are the most advanced set of RGB filters for deep-sky imaging available today.

During the design of the Deep-Sky RGB filters, we closely examined the sensitivity curves of today’s popular CCD cameras. We created one set of filters for all sensors, ranging from KAF- and KAI-sensors to the chips made by Sony. This allows you to take 1:1:1 ratio RGB exposures with minimal tweaking during processing for perfect colors in your image.

The transmission curves and coatings on the new Deep-Sky RGB filters are engineered to eliminate halos and reflections, even with bright stars in the field of view, allowing you to capture faint nebulae and galaxies with incredible detail.

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

Additional note for observers working under light-polluted skies:
If your observing site suffers from light pollution, you should try using our 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 color channels while blocking nearly all unwanted artificial light pollution. Customers who replaced the Lx filter with the CLS-CCD are amazed by the increased quality of their data. This small change allows for much deeper imaging from light-polluted locations.
