TS Optics 1.25" Colour Filter - Dark Blue #38A from 100mm
Enhances contrast on moon, planets and comets
TS Optics colour filters offer an improved contrast when viewing the moon and the planets. Each filter works out specific details by transmitting only specific parts of the visual spectrum. As a result the contrast of these details is boosted for better visibility.
Minimum aperture is 100 mm, suited for apertures of 150 mm or larger.
General contrast gain on the moon, off its terminator. Enhances contrast in Jupiter's and Saturn's cloud bands as well as surface details on Mars. In large aperture telescopes you may see cloud details on Venus. Good comet filter, because it boosts contrast in the comet's tail.
