With the StarSense Explorer 10" Dobsonian Optical Tube Assembly, Celestron has reinvented the Dobsonian telescope with the StarSense Explorer–the first Dobsonian that uses your smartphone to analyze the night sky and calculate its position in real time. This large-aperture Celestron StarSense Explorer is ideal for serious beginners, thanks to the app's user-friendly interface and detailed tutorials. It's like having your own personal tour guide of the night sky. The large aperture will ensure that you won't outgrow the telescope as you continue on your astronomical adventures.

Leave complicated star charts, imprecise planetarium apps, and computerized mounts behind. With the StarSense Explorer, locating objects has never been easier, faster, or more accurate. Within minutes of setting up the telescope, you'll be navigating the sky with confidence. Simply place your phone in the unique StarSense dock and launch the StarSense Explorer app.

After aligning your phone to the telescope's optics (a quick and easy procedure), the StarSense Explorer generates a list of celestial objects currently visible. Make your selection and arrows appear on-screen, guiding you as you move the telescope. When the object is ready to view in the eyepiece, the bullseye turns green. As you observe, listen to hundreds of audio descriptions and view detailed information about thousands of objects within the app's robust database.

With a large 10" Newtonian reflector optical tube, this telescope has enough light-gathering ability to bring out impressive detail in celestial objects while remaining remarkably portable. You can expect sharp, bright views of Jupiter's four Galilean moons, its cloud bands and Great Red Spot, the rings of Saturn, the gaseous glow of the Orion Nebula, dust lanes in the Lagoon Nebula, and our neighbor galaxy, Andromeda. Compared to the StarSense Explorer DX 130 AZ, the 10" Dobsonian has 380% more light gathering area, providing better views of faint objects.

All mirror surfaces are coated with Celestron's XLT optical coatings to visibly increase contrast and light throughput for brighter views. With XLT, you'll be able to discern subtle details while viewing the moon and planets, as well as faint galaxies and nebulae. The mirrors are made of low-expansion optical glass, which helps ensure the best images under changing environmental conditions. This telescope also comes with a high-quality 2" Crayford focuser. The Crayford design provides precise and smooth movements without focus shifting. It also includes a 2" to 1.25" adapter and a 2" extension tube, so you can use virtually any 1.25" or 2" telescope eyepiece with your StarSense Explorer Dobsonian. The focuser also features a thumbscrew so you can lock in the sharpest focus.

Even if you live in a light-polluted city location, the Celestron StarSense Explorer 10" Dobsonian is advanced enough to easily pick out Jupiter, Saturn, open star clusters like the Pleiades, double stars like Alberio, the Orion Nebula, Andromeda Galaxy, and more of the best and brightest celestial objects. But if you can take the telescope to an even slightly darker location, more objects will become visible. With this 10" Dobsonian and relatively dark skies, hundreds of fascinating objects are well within your reach. Transporting your StarSense Explorer Dobsonian is easy thanks to the ergonomic carry handles located at the balance point of the tube. Dust covers are also included for the front of the tube and the focuser.

Celestron's StarSense Explorer works with most modern smartphones, including iPhone 6 and up, and most devices running Android 7.1.2 or later manufactured since 2016.

The StarSense Explorer uses patented technology and your smartphone to determine exactly where the telescope is pointed in the night sky. A Lost in Space Algorithm (LISA), like the ones satellites use in orbit to correctly orient themselves, helps the app match star patterns it detects overhead to its internal database. While other astronomy apps may claim that they can help you find objects, they rely exclusively on the phone's gyros and accelerometers, which aren't as accurate as LISA technology. No other app can accurately tell you when your target is visible in the eyepiece.

Q: 1. Can you attach a DSLR camera to it?

A: You are able to mount a DSLR camera onto the Celestron StarSense Explorer 114mm f/4 Tabletop Dobsonian Telescope two ways. One way is to remove the eyepiece, and replace it with a T mount, and the appropriate dedicated camera T mount adapter. To see what T mount adapter you need, it will depend on the actual DSLR you want to mount. For example, here is one for Canon DSLRs with the Canon EF mount: https://www.bhphotovideo.com/c/product/261256-REG/Celestron_93419_T_Mount_SLR_Camera_Adapter.html and here is a T mount: https://www.bhphotovideo.com/c/product/202135-REG/Celestron_93625_SLR_35mm_OR_Digital.html The other way to mount a DSLR camera onto the Celestron StarSense Explorer 114mm f/4 Tabletop Dobsonian Telescope, is by using the T mount adapter, and the Novagrade T-Mount Digiscoping Adapter connected to each other, and that way you can create photographs taking advantage of the magnification of the eyepiece, (When you replace the eyepiece you loose all the magnification of the eyepiece) https://www.bhphotovideo.com/c/product/1142995-REG/novagrade_ua_00t1_01_t_mount_adapter.html
