Celestron Miscellaneous Telescope Accessories

These optical accessories, including star diagonals and polar axis finders, are designed to work with your Celestron telescope or mount. Please note that image erecting prisms are made for terrestrial use but are not necessary for astronomical observing. When it comes to objects floating in distant space, the notion of what is right-side-up or upside down is really just a matter of perspective.
