Smartphone Compatibility (works with most modern smartphones) Sturdy Altazimuth Mount Dazzling Views with High Quality Optics Perfect for the City or Dark Sky Sites
The Celestron Starsense Explorer LT 70AZ Refractor offers award-winning and patent-pending StarSense sky recognition technology which uses your smartphone to analyse star patterns overhead and calculate its position in real time. The StarSense Explorer app automatically generates a list of objects currently visible.
View planets, brighter nebulae and galaxies, star clusters, and double stars from the city. Or take your telescope to darker skies to view faint, deep sky objects. The manual altazimuth mount with altitude slow motion adjustment with a sliding rod makes it easy to follow the on-screen arrows to your desired target. When the bullseye turns green, it's ready to view in the telescope's eyepiece.
Solar Warning:
Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result.
Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
