Celestron Dew Shield Foamex for 5" Schmidt Cassegrain Telescopes.

Celestron offers a complete line of rugged, but soft Foamex plastic lens shades that can be put away flat after usage. They use a thicker material and won't crack easily as other manufacturer's products do. The quality level is a step above all others as all material is sewn (not glued in some places) for a long life.
