The Galileo G-545 is great for beginners and casual star gazers alike. It makes an excellent first refracting telescope for your kids or grand kids. Terrestrial viewing is extremely easy due to the included 90° diagonal mirror which produces a totally erect image. The mount is attached to a very sturdy, fully adjustable, pre-assembled metal tripod with rubber feet. The Galileo G-545 optical tube assembly features a 500mm focal length. The objective lens is an 45mm objective lens. The finderscope is 3x and features a crosshair reticle which helps by getting the observer behind the telescope without losing the surrounding field of view when targeting objects. Included with the Galileo G-545 are a 6mm eyepiece and a 20mm eyepiece. Gender: unisex.
