True astronomical refractor telescopes with no erecting lens, prisms, or mirrors added will produce an upside down image, so when you switch to viewing terrestrial (land) subjects, it can be awkward and difficult. The Cassini 1.25" Erecting Prism 2x Flip Barlow Lens extends your refractor telescope's abilities for terrestrial use by correcting the orientation of the image in your viewfinder to a right side up position. An on/off knob on the side allows you to toggle the built-in 2X Barlow lens to double the magnification of your existing lenses.
