Description
The Celestron StarSense Autoguider is an all‑in‑one solution that makes operating your telescope easier and more successful than ever. This compact, powerful device attaches to your Celestron mount, improves GoTo accuracy, and helps you effortlessly capture sharp, long‑exposure astrophotos. Whether you’re just starting in the hobby or have years of experience, this accessory helps you make even more of every clear night.
The StarSense Autoguider automatically selects reference stars for alignment at the push of a button—you don’t have to do anything. Celestron’s patented StarSense technology recognizes star patterns in the sky and compares them with the onboard database so the telescope knows its orientation. No more manually slewing and centering alignment stars—you can focus on what matters: observing and imaging.
Precise GoTo: Maximize Your Pointing Accuracy
Celestron mounts are already known for their high pointing accuracy, and your mount becomes even more precise with the StarSense Autoguider. Your targets will now appear not just in the field of view, but exactly in the center of your eyepiece or camera—even at high magnification or with a small sensor.
Autoguiding: Achieve the Perfect Image
Astrophotography is one of the most exciting activities for telescope owners. But for flawless captures, you need an autoguider—it makes tiny adjustments automatically so your telescope stays locked on target for long durations. Classic autoguiding setups are complicated and expensive, typically involving a guide scope, a second camera, and a separate computer. The StarSense Autoguider replaces all that—making it accessible even to beginners ready to dive into the astrophotography adventure. Your subjects will be crisp and clear, and background stars will stay sharp—not trailing or distorted by tracking errors.
Polar Alignment Assistance: Align Your Mount Perfectly
Many users have found that with the StarSense Autoguider’s pointing precision, you no longer need perfect polar alignment for visual observing or casual imaging.
But if you want the best results, the StarSense Autoguider makes polar alignment much easier. Just follow the instructions on the hand controller or CPWI software, and you can fully polar-align your mount in about 5 minutes.
High‑Quality Four‑Element Optics
The StarSense Autoguider features a four-element optical design calculated by the renowned designer Mark Ackermann. Its unique configuration delivers sharper images than other mini guide scopes. The tube includes a 2″ filter thread so you can add an IR-pass filter for alignment in twilight, or a neutral density filter for daytime focusing.
The unit also contains an onboard computer and a high-sensitivity monochrome Sony IMX290LLR CMOS sensor—working together to provide exceptional tracking accuracy. You can even view the camera feed live on your PC.
Advanced Control Options
Advanced users will appreciate the ability to fine-tune their autoguider settings in CPWI. You can enable dithering to slightly shift the camera between exposures, maximizing detail during post-processing.
With CPWI, you can also track a comet. Simply select the comet from the database—containing over 100,000 celestial objects and regularly updated online. Tracking a fast-moving comet directly will yield better results than following background stars.
And the best part: You can expect more exciting features throughout the lifetime of the StarSense Autoguider. Future firmware updates are free—no subscription fees. Celestron engineers continually enhance functionality, and a simple firmware update brings your device to the latest version.
Compatible with Your Existing Telescope
You decide how to control the StarSense Autoguider. Choose between the NexStar+ hand controller on compatible Celestron mounts or CPWI software via cable or Wi‑Fi (using the SkyPortal WiFi module or a mount with built‑in Wi‑Fi). The autoguider also works seamlessly with other Celestron accessories.
The StarSense Autoguider is compatible with most current Celestron GoTo mounts—both alt-azimuth and equatorial. Check the table below to see if your mount is supported.
Note: For telescope kits pre‑installed with the StarSense AutoAlign module, you’ll need an additional NexStar+ hand controller to operate the StarSense Autoguider. (The StarSense Autoguider is only compatible with the NexStar+ controller—not the StarSense hand controller.)
