Product Description
Celestron has reinvented the Dobsonian telescope with 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 in your astronomical adventures.
Dock, Launch, Explore
Leave complicated star charts, imprecise planetarium apps, and computerized mounts behind. With 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), 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.
High-Quality Altazimuth Base
An ultra-stable Dobsonian base provides a sturdy foundation for StarSense Explorer. It features large diameter altitude bearings with variable tensioning, Teflon azimuth bearings, and braces on the side panels for extra stability (unlike most 8-inch Dobsonian bases). The altitude bearings provide a smooth up-and-down motion while the integrated altitude brake system allows you to adjust the tension along the altitude axis for smoothest motion even with slight imbalances. The panning knob on the telescope tube provides an ergonomic grip so you can precisely point the telescope without introducing heat from your hands into the optical system. As celestial objects appear to drift across the night sky, you'll be able to easily follow them with minor adjustments to the telescope’s position.
Dazzling Views with High-Quality Optics
With a large 8-inch 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 8-inch Dobsonian has 240+% more light gathering area, providing better views of faint objects.
All mirror surfaces are coated with our 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-inch Crayford focuser. The Crayford design provides precise and smooth movements without focus shifting. It also includes a 2-inch to 1.25-inch adapter and a 2-inch extension tube, so you can use virtually any 1.25-inch or 2-inch telescope eyepiece with your StarSense Explorer Dobsonian. The focuser also features a thumbscrew so you can lock in the sharpest focus
