Celestron 94009 Lens Shade for C6 and C8 Tubes (Black)
Also called a dew shield, a lens shade 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 lens shade can accommodate both 6" and 8" Schmidt-Cass grain 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.
