The Celestron C5 127mm f/10 50x Spotting Scope is the ideal choice for the serious bird-watcher, nature lover, amateur astronomer, or anyone who enjoys beautiful views, either from home or in the field. With its generous 5" aperture, the C5 Spotter will easily outperform smaller-aperture spotting scopes. This is a versatile optical tool with a minimum close-focus range of 20' to make it ideal for observing plant life, wildlife, birds, or insects, and since it accepts any 1.25" eyepiece the C5 can also be used as an astronomical telescope. The scope can easily be transformed from a powerful spotting scope to a high-performance 1250mm f/10 telephoto lens with the use of the optional T-adapter and camera-specific T-ring. Celestron offers the C5 here without a tripod, but includes a 1/4"-20 mounting block so it can easily be attached to many photo, video, and field tripods with a payload capacity of at least 6 pounds. The block has multiple holes along its length for proper placement to achieve the optimum balance.
