A dew shield is an essential accessory that protects your optical tube from excess moisture forming condensation on the corrector lens. A lens shade also helps block out stray light outside the path of the telescope for better viewing and astroimaging.
This versatile dew shield can accommodate both 6” and 8” Schmidt-Cassegrain optical tubes. Choose the outer Velcro strip for larger tubes and the inner strip for smaller tubes to customize your fit. Also compatible with the 8” EdgeHD optical tube.
