Celestron Astro Fi 130mm f/5 Reflector Telescope

Optically, the scope sports a large 130mm aperture and a short 650mm focal length to produce a fast focal ratio that can resolve deep sky objects that smaller refractor-style scopes cannot, such as splitting binary stars or separating star clusters. With highly-reflective aluminum and SiO₂ (quartz) mirror coatings, light loss is limited so you can make detailed observations of the Moon, view planets and distant nebulae, and get great wide-field views of the sky for comet watching and asteroid hunting. This complete observation rig includes the optical tube assembly, a motorized mount, an aluminum tripod, two eyepieces, and a red-dot finder.

The OTA is mounted on a single-arm motorized alt-az mount. Guiding the mount is the SkyPortal app. Packed with over 120,000 objects it is designed to help users set up quickly and start observing faster. The app offers align aids, can automatically find objects in the night sky and even offers guided tours of the most interesting objects overhead on any given night. The mount runs on eight user-supplied AA batteries, and the entire rig assembles and breaks down without the need for tools so set up is easy and you can start observing sooner.
