A Lens Shade/Dew Cap is a tube designed to wrap around the front end of your SCT telescope and reduce the amount of dew that builds up on the corrector plate. It also serves as a Len Shade by preventing stray light from falling on the corrector plate, which greatly improves contrast.
Celestron offers a complete line of rugged, but soft Foamex plastic lens shades that can be stored flat after usage. They are made from a thicker material that won’t crack under temperature extremes. The quality level is a step above all others as all material is sewn (not glued) for a long life.
