Dew buildup is one of the most common challenges for amateur astronomers. There’s nothing more frustrating than setting up your telescope, finding the perfect celestial target, and then having your view fogged up by condensation. But don’t worry—reducing dew buildup on your telescope lenses is easier than you think. With the right techniques and tools, […]
