TS Optics professional 2" L-RGB filter set for astrophotographyWith
this LRGB filter set, you can take color images of celestial objects
with monochrome CCD cameras. This kind of deep-sky photography has a few
advantages over the astrophotography with color cameras:
- MONO CCD 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 camera is higher
than the one of a comparable colour camera, so, with these L-RGB
filters, dimmer objects are within reach at the 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 luminance 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.
Advantages of the 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. Over 92% of the visible light are transmitted
- 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 filters are durable through a scratch-resistant coating.
- The TS LRGB filters have an identical thickness to avoid readjusting of the focus.
