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