Bill explains how filters work, why you might use different filters and what a photo taken through a filter looks like. ... the colours are mixed up in any one of a number of ways. The image taken through the red filter might eventually come out as … WitrynaBaader UV/IR-Cut / L-Filter – CMOS-optimized. Beautifully engineered filters to use in. The long story short goes like this: we needed an UV cut filter with a cut-off wavelength in range of 400-420nm. The issue was we needed the filter at an "impossible" size, of precisely 5.6mm diameter.

Witryna31 gru 2008 · The Light Red Filter is another great filter for use on Mars, Jupiter, and Saturn, but because of lowered light transmission, it may not perform well for 6"; and smaller telescopes. It carries out many of the same functions as the #21 and the #15, but with more contrast, bringing out marginally defined blue-green surface detail.
