The 1.25" blue filter Nr.80A from Explore Scientific is designed to enhance your planetary observations by accentuating the contrast of atmospheric details on Mars, Jupiter, Saturn, and Venus. This filter facilitates the visualization of clouds on Mars and darkens the red structures, making Jupiter's Great Red Spot more visible. It also highlights the rings of Saturn and sharpens the atmospheric details of Venus. By slightly reducing brightness, this filter prevents overexposure while increasing overall contrast.
