Celestron StarSense Autoguider V2

• Automatic Alignment: Thanks to Celestron's patented StarSense technology, the telescope aligns itself to the night sky in about three minutes – without any user input.
  Precise GoTo: Improves the positioning accuracy of your Celestron mount and places celestial objects in the center of the field of view, even with high-magnification eyepieces and small camera sensors.
  Autoguiding: Precisely tracks celestial objects, allowing pinpoint star detail even in long-exposure astrophotography. Eliminates the need for a separate autoguiding camera, guidescope, and guiding computer.
  North Alignment Assistance: Guides you through a simple, automatic process to best align an equatorial mount.
  High-quality four-lens optics: Unique optical design by renowned optical designer Mark Ackermann, with sharper optics than other mini guidescopes.
  Multiple control options: Use your NexStar+ hand controller or the CPWI telescope control software via a wired or wireless PC.

  StarSense Autoguider
  
  The Celestron StarSense Autoguider is an all-in-one solution that makes operating your telescope easier and more successful than ever before. This small, powerful device connects to your Celestron mount, increases goto accuracy, and helps you capture sharp, long-exposure astrophotography with minimal effort. Whether you're just starting out in the hobby or have years of astrophotography experience, this accessory will help you make even more effective use of clear nights.
   

Automatic Alignment: Ready to observe in minutes

The StarSense Autoguider automatically searches for the reference stars for alignment at the touch of a button – you don't have to do anything else. Celestron's patented StarSense technology detects star patterns in the sky and compares them with the built-in database so the telescope knows where it's pointing. You no longer have to manually move to and center alignment stars, but can focus on what matters most – observing and photographing.

Precise GoTo: Maximize Positioning Accuracy

Celestron mounts are already known for their high positioning accuracy, but your mount will be even better when you use the StarSense Autoguider. Your targets are no longer just in the field of view, but exactly in the center of the eyepiece or camera – even at high magnification or with a small camera sensor.

Autoguiding: Create the Perfect Image

Astrophotography is one of the most exciting fields for telescope owners. But for perfect images, you need an autoguider – it automatically makes the small adjustments necessary to keep the telescope perfectly aligned to a target in the sky, even over long periods of time. Classic autoguiding solutions are complicated and expensive. They usually involve a guide scope, an additional camera, and a computer. With the StarSense Autoguider, all of this is unnecessary – and even beginners can dive headfirst into the adventure of astrophotography. Your subjects will be captured clearly and sharply in the image, and the background stars will remain pin-sharp and no longer distorted into lines or hooks due to tracking errors.

Assistance with North Alignment: Set up the Mount for the Best Possible Position

Many users have become convinced that with the StarSense Autoguider, they can achieve such precise goto that they no longer need to properly align their equatorial mount when observing visually or only occasionally taking photographs.

But if you want to achieve the best results, the StarSense Autoguider makes your job much easier. Simply follow the instructions on the hand controller or in the CPWI software, and you can fully align the mount within 5 minutes.

High-quality, four-lens optics

The StarSense autoguider uses a four-lens optical design designed by renowned optical designer Mark Ackermann. This unique construction delivers a sharper image than other mini guide scopes. The tube has a connection thread for 2" filters. This allows you to use an IR pass filter to set up the telescope at dusk, or a neutral density filter for focusing during the day.

The device also includes a built-in computer and a high-sensitivity monochrome Sony IMX290-DLL CMOS sensor, all of which work together to achieve exceptional tracking accuracy. If you wish, you can also view the camera image live on your PC.

Options for Advanced Users

Experienced users will appreciate the ability to further optimize their autoguider setup in CPWI. You can set dithering so that the camera moves slightly between shots, allowing you to get the most out of each individual image later during image processing.

CPWI also allows you to track a comet. Simply select the comet from the database, which contains over 100,000 celestial objects and is regularly updated online. If you want to focus directly on the fast-moving comet, you can use the following options: The results will be better than if you were tracking the fixed stars.

And best of all: You can look forward to even more exciting features throughout the lifetime of the StarSense Autoguider. Future firmware updates cost no additional money or subscription fees. Celestron engineers are constantly working to expand the functionality of our products, and with a simple firmware update, you'll be back up to date.

Compatible with your existing telescope

You decide how you want to control the StarSense Autoguider. You can choose between the NexStar+ hand controller on current Celestron mounts and the CPWI software, the latter either via a wired connection to your PC or via Wi-Fi (with the SkyPortal Wi-Fi module or a mount with integrated Wi-Fi). The autoguider also works with other Celestron accessories, ensuring everything harmonizes perfectly.

The StarSense Autoguider works with most current Celestron GoTo mounts, both alt-azimuth and alt-azimuth. the equatorial mounts. Check the table below to see if your mount is one of the compatible models.

Please note: for telescope sets with pre-installed StarSense AutoAlign module you need an additional NexStar+ hand controller to operate the StarSense Autoguider. (The StarSense Autoguider is only compatible with the NexStar+ hand controller and not with the StarSense hand controller.)
