In addition to operating as a superb telephoto lens, it can also be used as a terrestrial spotting scope or astronomical telescope. The lens comes standard with a photo tripod adapter block.
This Celestron Lens can also be used as a rich field telescope to observe deep sky objects. The model # is 81005.
