Baader 1.25" colour filter - red


Baader 1.25" colour filter - red

♦ Red long pass filter 610nm. Red filter with steep absorption edge. Filters out the H-alpha line from the visible spectrum.

♦ Blue and blue-green light is almost completely blocked, increasing contrasts between the bright zones and the dark bands on Jupiter and Saturn

♦ The most interesting filter for observing the polar caps of Mars

♦ Optimal filter for daytime observation of all planets

♦ 7-layer antireflection coating on both sides with only 0.25% residual reflection per surface represents the most elaborate coating (= antireflection coating!) ever undertaken for color filters.
