TS-Optics LRGB Filter Set 2" - CCD/CMOS Interference Filter Set
TS professional L-RGB 2" filter set for astrophotography - colour images with monochrome CCD/CMOS cameras.
The set includes four 2" filters - Luminance, Red, Green and Blue. True interference filter for very good contrast and balanced colour weighting, with very high transmission at the same time. The filters are durable through a scratch-resistant coating. The TS L-RGB filters offer a neat anti-reflection coating. Due to the precise transmission curves, over 92% of the visible light are transmitted, whereas the infrared light is reliably blocked. The filters are stress-free mounted in a high-quality aluminum cell with standardized filter threads on both sides.

TS Optics professional 2" L-RGB Filter Set for astrophotography
With the TS LRGB filter set, you can take color images of celestial objects with monochrome CCD/CMOS cameras. This kind of deep-Sky photography has a few advantages over the astrophotography with color cameras: MONO CCD/CMOS cameras have a higher resolution than color cameras with the same chip. Objects are shown with more details. Due to the steep edges of the filters, high quality colour images are possible even close to towns, as the disturbing light pollution is filtered out. The sensitivity of a mono CCD/CMOS camera is higher than the one of a comparable colour camera, so, with these L-RGB filters, dimmer objects are within reach at he same exposure time. Usually, the colour brilliance of an L-RGB image is higher than the one of a normal color image, as you can control the colour weighting during image processing. With the luminaance filter, you can generate a high-resolution luminance image and with the RGB filters you can create a splendid colour image. During image processing, you can mix the resolution of the luminance and the color of the RGB image.
The advantages of the TS L-RGB filters:
High transmission and steep edges offer a very high contrast. The colour weighting of the filters is well balanced. Infrared is cut off by each of the filters, for better sharpness and contrast. The surfaces are plane-parallel against unwanted ghost images. The surfaces are anti-reflective coated. The filters are mounted in high-quality aluminium cells with accurate filter threads. The TS LRGB filters have an identical thickness to avoid readjusting of the focus.
