The Skywatcher 10mm eyepiece allows you to use your reflector telescope to view objects on the ground. Reflector telescopes are typically cheaper than a Refractor telescope of the same imaging power.

However, they are not designed to see the earth and produce images that are upside down. An erecting eyepiece corrects the orientation of the image making it more usable for viewing terrestrial objects. High-quality construction and superior optical components ensure you get clear images of the objects you want to see.
