StarSense Explorer, the first Dobsonian telescope that uses your smartphone to examine the night sky and compute its position in real-time, has been redesigned by Celestron as a Dobsonian telescope. Due to its user-friendly interface and thorough lessons, the Celestron StarSense Explorer 10" with a wide aperture is perfect for serious beginners. It's like having your very own personal astronomy tour guide. You won't outgrow the telescope as you continue your astronomical explorations thanks to the huge aperture.

Dock, Launch, Explore
Leave computerised mounts, intricate star charts, and inaccurate planetarium software behind. Finding objects has never been simpler, faster, or more accurate than with StarSense Explorer. You can confidently navigate the sky after only a few minutes of telescope setup. All you need to do is insert your phone into the special StarSense dock and open the StarSense Explorer app.

A list of celestial objects that are now visible is generated by StarSense Explorer after you quickly and easily align your phone with the telescope's optics. Once you've made your choice, arrows will show up on the screen to direct you as you move the telescope. The bullseye becomes green when the object is ready to be seen through the eyepiece. View detailed information on thousands of things while you observe and listen to hundreds of audio descriptions from the app's extensive database.

Superior Altazimuth Base
StarSense Explorer has a strong base in the form of an ultra-stable Dobsonian. It has braces on the side panels for further stability (unlike most 10inch  Dobsonian bases), large diameter altitude bearings with variable tensioning, Teflon azimuth bearings, and other features. The integrated altitude "brake" mechanism lets you adjust the tension along the altitude axis for smoothest motion even with tiny imbalances, while the altitude bearings give a smooth up-and-down action. To accurately orient the telescope without heating up the optical system with your hands, use the ergonomic panning knob on the telescope tube. You can easily follow celestial objects as they appear to wander across the night sky by making small adjustments to the position of the telescope.

High-quality optics and stunning views
This telescope is extremely portable and includes a huge 10 inch Newtonian reflector optical tube with ample light-gathering capability to reveal stunning clarity in celestial objects. The four Galilean moons of Jupiter, its cloud bands, the Great Red Spot, Saturn's rings, the gaseous glow of the Orion Nebula, the dust lanes in the Lagoon Nebula, and our neighbour galaxy, Andromeda, may all be seen with clarity and brightness. The 10" Dobsonian has 380+ percent larger light gathering area than the StarSense Explorer DX 130 AZ, offering greater views of dim objects.

Our XLT optical coatings are applied to all mirror surfaces to tangibly boost contrast and light throughput for brighter images. The Moon, planets, dim galaxies, and nebulae can all be seen with XLT, and you'll be able to see minute features in them. Low-expansion optical glass, which is used to make the mirrors, helps to ensure the best images despite changing climatic circumstances.

The 2 inch Crayford focuser that comes with this telescope is of the highest calibre. With no focus changing, the Crayford design offers accurate and fluid movements. You can use your StarSense Explorer Dobsonian telescope with just about any 1.25 or 2 inch telescope eyepiece thanks to the addition of a 2 to 1.25 inch adapter and a 2 inch extension tube. A thumbscrew is also included on the focuser, so you can secure the clearest focus.

Ideal for Urban or Dark Sky Locations
The Celestron StarSense Explorer 10 inch Dobsonian is sophisticated enough to easily distinguish Jupiter, Saturn, open star clusters like the Pleiades, double stars like Alberio, the Orion Nebula, the Andromeda Galaxy, and more of the best and brightest celestial objects, even if you live in a light-polluted city location.

However, additional objects will become visible if you can move the telescope to a spot that is even a little bit darker. You may easily access hundreds of fascinating things with this 10" Dobsonian and reasonably dark sky.

The ergonomic carry handles at the balancing point of the tube and base make it simple to move your StarSense Explorer Dobsonian. The focuser and the front of the tube both have dust shields.

Smartphone Compatibility
The majority of recent smartphones, including those with an iPhone 6 or later, and those running Android 7.1.2 or later that were produced after 2016 are compatible with Celestron StarSense Explorer. Click here for a complete compatibility list.

Technology for Patented StarSense Sky Recognition
Your smartphone and patented technology from StarSense Explorer are used to pinpoint precisely where the telescope is positioned in the night sky. The software uses a Lost in Space Algorithm (LISA) to compare star patterns it observes overhead to its internal database. Satellites employ LISAs to correctly orient themselves while in orbit.

Other astronomy apps may claim to be able to assist you in object discovery, but they only use the phone's gyros and accelerometers, which are less precise than LISA technology. No other app is able to predict with such accuracy when your target will be visible in the 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.
