The Power of GPS GoTo Technology

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 and advanced observers alike, 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. Advanced observers will appreciate the ease of use and spectacular views the StarSense Explorer 12” Dobsonian provides.

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 many 12” 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 12" Newtonian reflector optical tube, this telescope has enough light-gathering ability to bring out impressive detail in celestial objects. 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 other StarSense Explorer Dobsonian telescopes, the 12” Dobsonian has 2.25 more light gathering ability than the 8” and 2.25x more light gathering ability than the 10”, 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” 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.

Perfect for the City or Dark Sky Sites

Even if you live in a light-polluted city location, the Celestron StarSense Explorer 12” Dobsonian is advanced enough to easily pick out Jupiter, Saturn, open star clusters like the Pleiades, double stars like Acrux (the "tail" of the Southern Cross, the Orion Nebula, Omega Centauri, 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 12" 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 and base. Dust covers are also included for the front of the tube and the focuser.

Smartphone Compatibility

Celestron 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. For a complete compatibility list, click here.

Patented StarSense Sky Recognition Technology

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.

Enhance Your Setup

Keep your phone charged all night while exploring with your StarSense Explorer by adding the PowerTank Glow 5000 to your must-have accessories (sold separately). This 2-in-1 accessory was made with the StarSense Explorer Dobs in mind, it has a red flashlight PLUS a USB power bank for charging mobile devices in the field. Connect the PowerTank Glow 5000 to the two posts at the front of the StarSense Explorer dock with the included bands so it is held in a convenient location for charging your smartphone while in use.

To achieve the sharpest views faster, we recommend pairing the StarSense Explorer 12” Dobsonian with the USB Cooling Fan for Dobsonian Telescopes (sold separately). The fan cools the primary mirror to the ambient outdoor temperature faster, leaving you more time to observe. It mounts directly onto the rear cell of the Dobsonian and works with any USB power source.

RASA Optical Technology: Unleashing the Power of Light

At the heart of Celestron Origin Mark II lies the patented Rowe-Ackermann Schmidt Astrograph (RASA)—a landmark advancement in optics. In the RASA design, the imaging sensor lies at the front of the telescope tube, not the back, creating an ultra-fast f/2.2 system with an extraordinarily wide field of view while providing sharp images to the edge. Since it launched in 2014, RASA technology has become the go-to choice for space surveillance and satellite tracking. National defense contractors, professional research astronomers, and governments trust RASA to detect tiny pieces of debris and space junk, keeping our vital communications satellites safe in orbit. For Origin, Celestron’s optical engineers developed a brand-new 6” RASA with all the same capabilities of an observatory-grade instrument in a grab-and-go package.

Thanks to RASA, Celestron Origin Mark II is in a class of its own, far outperforming other telescope designs. RASA simply delivers more photons in less time than a smaller and slower Newtonian reflector, refractor, or other entry-level telescope tube. RASA’s unique combination of speed, aperture, and performance ensures unparalleled image detail, even during short exposure times.

Now Equipped with the Celestron Origin 678C Camera

Celestron Origin Mark II now comes equipped with the Origin 678C Camera—a next-generation upgrade featuring Sony’s latest Starvis 2 CMOS technology. With 8.4 megapixels, ultra-fine 2.0 μm² pixels, and a modern 16:9 aspect ratio, this advanced sensor delivers higher resolution and increased sensitivity.

Precision-matched to Origin’s fast f/2.2 RASA optics, the 678C Camera captures fine structure in galaxies, nebulae, and star clusters. Whether you're new to astrophotography or an experienced imager, you’ll enjoy clean, crisp results—ready to stack, share, or admire on your device in near-real time.

Turning Every Backyard Observer into an Astroimager

Celestron Origin Mark II introduces a paradigm shift in astrophotography with its built-in AI algorithms. As the telescope captures data, these intelligent algorithms automatically process every frame in real time. It’s important to note that the AI imaging processing in the Origin app is not generative AI. It does not colorize or add to your image data in any way. It simply sharpens and enhances your images using the same processing techniques an advanced astroimager would use.

The images you create with Celestron Origin Mark II are 100 percent your own data, optimized to look its best. The technology works in real-time on your live-stacked images and is also applied to the final stacked master. The result is a breathtaking display of celestial objects, rich with colour and detail beyond what the human eye could perceive in an eyepiece. And you can always adjust the images yourself using the manual controls. Thanks to the Celestron Origin Mark II, astroimaging is now accessible to enthusiasts of all skill levels, including those who have never used a telescope before.

A Universe at Your Fingertips: StarSense Technology & the Origin App

Setting up Celestron Origin Mark II is a snap, thanks to its automated initialization process powered by StarSense technology. Place Origin outside, turn it on, and connect to the app. Then, you can choose to remain with your telescope or head indoors. In less than two minutes, Origin focuses itself, scans the night sky, autonomously aligns itself by matching star patterns overhead to its internal database, and notifies you that it’s ready to begin your astronomical adventure.

The Celestron Origin Powered by SkySafari™ app, developed in collaboration with Simulation Curriculum offers an intuitive planetarium interface that simplifies navigation through the night sky. Using the planetarium view, hold your device up to the sky to look around using “compass mode”, and tap on any object you want to see (the best ones are highlighted).

Ready for More? Advanced Features

As you grow in the hobby alongside Celestron Origin Mark II, it will continue to support you with more advanced features and functionality. For example, Origin has a built-in filter drawer that accepts standard 1.25” and 2” format filters. This allows you to install optional filters, which can be especially useful in imaging nebulae in light-polluted environments like the typical suburban backyard. For imaging broadband objects like galaxies and star clusters or objects from dark skies, remove the filter for more light-throughput and brighter images. Experiment with removable and interchangeable filters for results you can’t achieve with other systems’ fixed filters.

If you would like to try advanced image processing, Celestron Origin Mark II again has you covered. It can automatically save all your raw images, which you can retrieve by plugging in a USB thumb drive or by connecting to Origin’s built-in WiFi network to download the files to your computer wirelessly. Then, import them into your favorite software for manual editing and stacking.

And how about putting Origin to work for you while you sleep? That’s no problem with the scheduled observations feature. Just tell the app which objects you want to capture. You’ll wake up to an array of spectacular images.

Expand Your Astroimaging Possibilities with Celestron Origin

Celestron Origin Mark II delivers stunning deep-sky images right out of the box. But for experienced astrophotographers interested in experimenting with longer manual exposure times, there’s now an exciting new way to fine-tune performance: equatorial wedge mode, enabled by the Wedge for NexStar Evolution and the optional StarSense Autoguider.

By aligning Celestron Origin Mark II with Earth’s rotational axis, the wedge eliminates field rotation during tracking. This enables longer sub-exposures and allows imaging near or at zenith—ideal for capturing fainter details with greater clarity, since zenith (straight up) is generally the darkest part of the night sky. As with any equatorial setup, polar alignment is required before use, but the app will take you through an automated routine that makes it easy.

For exposure times beyond 30 seconds, we recommend pairing the wedge with the StarSense Autoguider. While Celestron Origin Mark II excels at short exposures (10–15 seconds), automatically rejecting frames with minor tracking errors, the Autoguider boosts tracking precision for longer manual exposures—reducing rejected frames and maximizing image quality. Together, the equatorial wedge and StarSense Autoguider offer a powerful toolkit for advanced users pursuing specialized longer-exposure imaging.

Gain a New Perspective Here on Earth

In addition to revealing distant worlds, Celestron Origin Mark II can also capture incredible views of land-based objects on Earth, day or night. During the day, you can manually slew to capture landscapes and scenery. At night, Origin’s fast optics and sensitive camera allow you to see things in very dim ambient conditions for almost night-vision-like performance. Look around your yard or campsite at night to see what you may be missing!

Take Your Astroimaging Studio Anywhere

Celestron Origin Mark II is a portable system that doesn’t require external WiFi or 5G networks, so you can easily take it to remote dark skies in any car. Perfect for exploring our southern skies from out in the bush!

The optical tube, mount, and tripod all easily assemble and disassemble without tools. Each component weighs less than 16 lb. Optional carry cases are also available.

Your Celestron Origin Mark II system comes complete with everything you need to become an instant astronomer:

Future Upgrades

When you invest in Origin, you can count on Celestron’s engineers as your long-term partners in astronomy. Our technical teams are hard at work developing even more upgrades and enhancements for your Origin. For example, we provide access to Origin’s camera for potential future upgrades as technology improves. We’re also developing all-new functionality for your Origin and the Origin app.

Here’s a sneak preview of what we’ll be rolling out in the coming months:

Mosaic Mode:- Capture wider fields of view by stitching multiple images together.

A:
That’s correct. Because the human eye is less efficient than CMOS sensors at low light levels, we are removing it from the equation. Origin’s sensor “sees” more photons in less time than your eye could and then delivers the images it captures to your phone or tablet. The result is “almost real-time” visual observing without an eyepiece. With Origin, you see much more detail in faint, deep-sky objects than you would through the eyepiece of a much larger telescope under dark skies.

Celestron C6

Striking a comfortable balance between power and portability, the Celestron C6 -A XLT OTA 6" f/10 Schmidt-Cassegrain Telescope is an ideal choice for observing objects within or beyond our solar system. It features a Schmidt-Cassegrain optical system consisting of a corrector plate, spherical primary mirror, and secondary mirror that work together to reduce spherical and chromatic aberrations to crisp and clear high-resolution images with accurate color representation with distortion - especially at the edges. Complementing the optical system is the proprietary StarBright XLT optical coating system, which improves light transmission and reflectivity across the entire visual spectrum. Perfect for mounting on a Celestron Advanced VX or alternatively a Skywatcher HEQ5 Pro.

• 6" Schmidt-Cassegrain Optical Tube Assembly
• Aluminum Optical Tube
• Celestron's premium StarBright XLT coatings
• 1500 mm focal length (f/10)
• 25 mm eyepiece included (60x)
• Visual back allows for use with 1.25" accessories
• 6x30 finderscope to help accurately find objects
• Star diagonal provides more comfortable viewing position when observing objects that are high in the sky
• Includes dovetail rail compatible with CG-5 Advanced Series mount

The Celestron C9.25-A is an unusual size with its 9.25” aperture and 2350 mm focal length, but many consider it to be the Goldilocks of optical tubes—not too big, not too small. This rugged aluminum optical tube is only 558mm long and weighs just 9kgs, making it easy to transport and set up. But the views are much more impressive than what you’d expect from such a compact instrument. The tube offers a focal ratio of f/10 with the added versatility of Fastar (see below).

It is equipped with Celestron’s patented StarBright® XLT optical coatings, which visibly increase contrast and light transmission for brighter deep space images and shorter exposure times. With StarBright XLT, you’ll be able to discern subtle details while viewing the Moon and planets as well as faint galaxies and nebulae.

The Celestron C9.25-A can be mounted on a multitude of computerized telescope mounts thanks to its CGEM-style dovetail bar. This iconic optical tube provides the best balance of portability, handling ease, light gathering ability and price ever offered to the amateur astronomer.

Fastar Technology

In 1997, CCDs were making a name for themselves in the astrophotography world, quickly supplanting traditional film photography thanks to their speed and convenience. This was the year that Celestron joined forces with the Santa Barbara Instruments Group (SBIG) to produce Fastar, a revolutionary add-on to Celestron’s hugely popular Schmidt-Cassegrain (SCT) optical system.

With Fastar, the SCT’s secondary mirror can be removed and replaced with a field-flattening lens assembly (sold separately by third party manufacturers) so that a CCD camera can be used in the front of the telescope at the f/2 focus of the instrument’s primary mirror. The potential of the Fastar system is staggering: exposures are 25 times shorter than if the camera was placed at the instrument’s native f/10 focus. Imagers can capture galaxies and nebulae with exposures of just 30 seconds.

StarBright XLT coatings

StarBright XLT is Celestron’s revolutionary optical coating system. It consistently outperforms all other coatings in the commercial telescope market. There are three major components that make up our StarBright XLT high-transmission optical system design:

• Unique enhanced multi-layer mirror coatings made from precise layers of aluminum, SiO2 (quartz), TiO2 (titanium dioxide), and SiO2 (silicon dioxide). Reflectivity is fairly flat across the spectrum, optimizing it for both imaging and visual observing.
• Multi-layer anti-reflective coatings made from precise layers of MgF2 (magnesium fluoride) and HfO2 (hafnium dioxide). Hafnium—a rare element that costs nearly $2,000 per kilogram—gives us a wider band pass than the titanium used in competing coatings.
• High-transmission water white glass is used instead of soda lime glass for the corrector lens. Water white glass transmits about 90.5% of light without anti-reflective coatings; that’s 3.5% better than uncoated soda lime glass. When water white glass is used in conjunction with StarBright XLT’s anti-reflective coatings, the average transmission reaches an astonishing 97.4.

The Celestron CPC 1100 GPS is a rock-solid dual fork arm mount and large aperture at an affordable price: that's what makes the CPC telescope a favorite among experienced amateur astronomers. Celestron's revolutionary SkyAlign plus an internal GPS make alignment a snap. Use the computerized hand control to quickly slew to over 40,000 celestial objects, then track your target precisely as it moves across the night sky. Imagers can place the CPC dual fork arm mount on an optional HD Pro Wedge to polar align it for long-exposure astrophotography. Thoughtful ergonomic design makes setting up and breaking down your CPC quick and painless.

Celestron C11-A XLT OTA Specifications

The Celestron C8-A is the direct (but much improved) descendent of Celestron’s revolutionary C8 that transformed the hobby of astronomy when it was unveiled in 1970. This rugged aluminum optical tube is only 17 inches long and weighs just 13 pounds, making it easy to transport and set up. But the views are much more impressive than what you’d expect from such a compact instrument. The tube offers 2032 mm of focal length and a focal ratio of f/10, with the added versatility of Fastar (see below).

It is equipped with Celestron’s patented StarBright® XLT optical coatings, which visibly increase contrast and light transmission for brighter deep space images and shorter exposure times. With StarBright XLT, you’ll be able to discern subtle details while viewing the Moon and planets as well as faint galaxies and nebulae.

The Celestron C8-A can be mounted on a multitude of computerized telescope mounts thanks to its CGEM style dovetail bar. This iconic optical tube provides the best balance of portability, handling ease, light gathering ability and price ever offered to the amateur astronomer.

Fastar Technology

In 1997, CCDs were making a name for themselves in the astrophotography world, quickly supplanting traditional film photography thanks to their speed and convenience. This was the year that Celestron joined forces with the Santa Barbara Instruments Group (SBIG) to produce Fastar, a revolutionary add-on to Celestron’s hugely popular Schmidt-Cassegrain (SCT) optical system.

With Fastar, the SCT’s secondary mirror can be removed and replaced with a field-flattening lens assembly (sold separately by third party manufacturers) so that a CCD camera can be used in the front of the telescope at the f/2 focus of the instrument’s primary mirror. The potential of the Fastar system is staggering: exposures are 25 times shorter than if the camera was placed at the instrument’s native f/10 focus. Imagers can capture galaxies and nebulae with exposures of just 30 seconds.

StarBright XLT coatings

StarBright XLT is Celestron’s revolutionary optical coating system. It consistently outperforms all other coatings in the commercial telescope market. There are three major components that make up our StarBright XLT high-transmission optical system design:

• Unique enhanced multi-layer mirror coatings made from precise layers of aluminum, SiO2 (quartz), TiO2 (titanium dioxide), and SiO2 (silicon dioxide). Reflectivity is fairly flat across the spectrum, optimizing it for both imaging and visual observing.
• Multi-layer anti-reflective coatings made from precise layers of MgF2 (magnesium fluoride) and HfO2 (hafnium dioxide). Hafnium—a rare element that costs nearly $2,000 per kilogram—gives us a wider band pass than the titanium used in competing coatings.
• High-transmission water white glass is used instead of soda lime glass for the corrector lens. Water white glass transmits about 90.5% of light without anti-reflective coatings; that’s 3.5% better than uncoated soda lime glass. When water white glass is used in conjunction with StarBright XLT’s anti-reflective coatings, the average transmission reaches an astonishing 97.4.

Capturing impressive deep-sky astroimages is easier than ever with Celestron’s Rowe-Ackermann Schmidt Astrograph (RASA 11) V2, the perfect companion to today’s top DSLR or astronomical CCD cameras. This fast, wide-field f/2.2 system allows for shorter exposure times compared to traditional f/10 astroimaging, without sacrificing resolution. Because shorter sub-exposure times are possible, your equatorial mount won’t need to accurately track over extended periods. The short focal length also lessens equatorial tracking demands. In many cases, autoguiding will not be required.

RASA 11 V2 builds on the legacy of Celestron’s Schmidt Cameras, which allowed astrophotographers to produce images with much shorter exposure times on film in the 1970s.

Today, with CCD sensor sizes as large as film or larger, the RASA 11 V2 offers a 43.3mm optimized image circle to capture pinpoint stars on the largest imaging chips. Optical performance for huge sensors with diagonals of up to 52mm wide is still excellent.

Combine this large image circle with a focal length of just 620mm and you have an instrument suitable for wide-field imaging, creating huge mosaics of the night sky, surveying, and even comet hunting.

Optical Performance
The RASA 11 V2 features optics with 4-element rare-earth glass for images free of false color and aberrations like coma and field curvature. The optical quality and spot size across the entire image circle are unprecedented for an astrograph in this price range—or even that of a much more expensive instrument. The design also provides minimal vignetting.

Advanced Features
RASA 11 V2 utilizes the Ultra-Stable Focus System (USFS). At the heart of this system is a precision linear ball bearing. The bearing serves to minimize focus shift (unwanted lateral motion of the primary mirror during focusing which causes shifting of the image) and mirror flop (movement of the primary mirror when the telescope is pointing to different positions in the sky). The USFS is also compatible with the optional Celestron Focus Motor (#94155-A). The integrated 12V DC MagLev fan reduces cooldown time and provides optimal airflow through the dust filtered optical tube.

Engineered as a complete astroimaging system, every component of the RASA 11 V2 is optimized for peak performance with DSLR and astronomical CCD cameras. Down to the thickness of the glass used in the included fully-multicoated optical window or optional imaging filter, every component of the system has been taken into careful consideration to work together seamlessly. The Dovetail CGE bars on the top of the optical tube provides a connection for use of optional accessories like a guidescope.

The Rowe-Ackermann Schmidt Astrograph (Celestron RASA 36), is a cost-effective optical system for space surveillance, Space Situational Awareness (SSA), other scientific applications, and advanced wide field astroimaging. It offers unprecedented value in aperture, speed, field of view, and optical performance. The RASA design has a convenient external prime-focus image capture location with a flat focal plane, providing small spot sizes to the edge of a wide field. The result is images free of optical defects like field curvature, off-axis coma, and astigmatism.

The 36 cm aperture version is the largest RASA Celestron manufactures; it is the biggest and fastest (f/2.2) optical instrument of its kind available off-the-shelf. Unlike most telescopes, which only focus visible light (400-700 nm), the RASA 36 cm focuses an extended spectral range (400-900 nm), allowing a brighter signal to be detected by a camera sensor. The RASA 36 cm also features a redesigned focus system, which ensures easy and stable focusing.

RASA 36 c sample back-focus distance (77.5 mm) accommodates a wide variety of imaging sensors. A custom camera adapter can be added for a field of view up to 4.4 degrees.

Important freight requirement RASA 36 is a professional-caliber, high-precision instrument. It is manufactured and aligned to an exacting standard to provide exceptional optical performance. The telescope has been packaged to ensure it retains alignment and resulting performance during transport. However, due to the weight, size, and known stresses of shipping via parcel service, Celestron has determined that the ideal transport is a palletized delivery via LTL truck freight. For all Australian deliveries, Celestron will ship via this method. Please contact us for further freight costs
