Tired of dust getting into your new telescope? Fear no more!

This dust cover /lens cap fits on by filling a 131mm inner diameter, like that on the Celestron 114 AZ or 114EQ. Any other scope with an inner diameter of 131mm should also work. The cat he's around the outside of the ring are slightly oversized intentionally because ever scope is different. Just shave/deburr them until you have a snug fit. 

This is my first model, be sure to let me know what you think, thank you!
