Celestron NexImage 20 Solar System Colour Imager

Product Description

Capture your own stunning images of the planets, Moon, and Sun (with solar filter) with the Celestron NexImage 20. Our team engineered this high-performance USB camera for serious astrophotography. With a powerful 20 MP back-illuminated CMOS sensor, NexImage 20 captures ultra-high-resolution images at 5240 x 3840 pixels, giving you crisp, detailed results ready for stacking, printing, and sharing online.

NexImage 20 is one of the best values in Solar System imaging today, delivering impressive detail and producing images that rival those from cameras costing hundreds more. It's an excellent way to get started with astroimaging—even from light-polluted city skies. If you can see a planet through your telescope, you can capture it with NexImage 20!

Advanced Sensor Technology
At its core is the AR2020 sensor, optimized for low-light conditions with 1.4 µm square pixels on a 7.3 x 5.4 mm sensor. This combination delivers impressive sensitivity (8.7 ke?/lux-sec) and allows you to capture fine surface features, even when atmospheric seeing isn’t ideal.

Includes a free download of Celestron’s iCap software to fine-tune exposure, gain, frame rate, and more—unlocking the sensor’s full potential.

Easy Installation
Even if you’re brand new to astroimaging, getting started with NexImage 20 is fast and straightforward. After installing the driver and iCap software, assemble the camera by threading it onto the included 1.25” nosepiece. Then insert it into your telescope’s eyepiece holder, connect the USB-C cable to the camera, and plug the USB-A end into your PC. That’s it; you’re ready to capture your first high-resolution images and videos!

Region of Interest for Speed & Efficiency
Imaging the Full Moon or Sun will use a large portion of the NexImage 20 sensor. But if you’re pointing your telescope at the planets, the Region of Interest (ROI) feature is a game changer. Instead of using the entire sensor, ROI lets you crop to focus on just your target. This boosts frame rates for smoother video while reducing file size. It also speeds up post-processing, especially when you’re stacking multiple frames.

Built-In Autoguiding Capability
Beyond imaging, NexImage 20 can perform double-duty in your advanced astroimaging kit. Use it as a precise autoguider for long-exposure, deep-sky astrophotography. With additional guiding hardware (not included), NexImage 20 helps advanced users lock onto their target and maintain tracking accuracy over time.
