Summary

A cover designed to just push in to the screw on shade so you dont have to unscrew it and screw on the original cap every time. Just grab this cover by the handle on the top and push it in and it should stay in pretty securely. Ife youre packing the scope in a bag and traveling with it though, Id just screw on the original cap to make sure it doesnt come loose.

It should work with the other etx scopes or other scopes entirely with a simmilar design if you scale it deppending on your scope but Ive only used it on an ETX70 and thats what its designed for.
