The Atik Horizon II is the follow up to our first ever CMOS Camera. It houses a 16MP sensor with exceptionally low read noise and incredibly fast read speeds. With our signature Atik blend of form and function, the Atik Horizon II provides a sensitive, high megapixel sensor at a competitive price point. This makes it a great option if you're looking to upgrade from DSLR, or have system that would benefit from shorter exposure times.

  • 16MP 4/3" CMOS sensor

  • 256mb DDR3 Image Buffer

  • ~1e- Read Noise

  • Cooling ΔT=>-40°C

  • USB 3.0


New Horizon II Modes

  • PowerSave Mode - Allows for the highest quality images to be taken.

  • Fast Mode - Takes advantage of the on board DDR memory to return a constant stream of images. Fast mode increases the frame rate of the Horizon II to 8FPS. This can increase to 100FPS through the use of subframing, and reaching 300FPS when used with Dusk.


With extensive experience in both hardware and software design, the Atik Horizon II continues its development in the world of deep-sky optimised CMOS cameras.

Mechanically, the Horizon II is based on our estblished 4-Series cameras, known for their power and adaptability. With a cyclindrical case measuring 74mm in diameter and 130mm in length, it's compatible with HyperStar systems from 8". The slight size increase on the 4-Series is to house a huge cooling delta of -40°C below ambient. This keeps thermal noise under control, wherever in the world you image from.

Advanced Hardware Deserves Advanced Software


The Atik Horizon II is natively compatible with our Infinity live stacking software to give you incredible views of the night sky in a near real-time environment. Not only is this great for video astronomers and public outreach, it also makes getting into astrophotography a breeze. Our on-the-fly image processing gets you up and running quickly, minimising the learning curve many people experience. However, our advanced functions ensure you are always in control as you steer your way through the night sky.

  • Live continuous stacking

  • Flexible histogram control, including auto-stretch functions

  • Live YouTube broadcast integration

  • Interactive session replay

  • Focus assist and monitoring tools

  • Save to FITs, PNG, JPG and TIFF formats


The Horizon II is also fully compatible with our renowned Artemis Capture and Dusk imaging software that gives you full control over your imaging. We also supply a full ASCOM driver so you're free to use it with your preferred astroimaging software. When used with Dusk, the Horizon II can not only be used as a cooled deep sky imaging camera but can also be used for high speed planetary imaging with frame rates reaching 300 frames per second using the ROI function.

Amp Glow Control


From the outset, the Horizon II has benefited from a built-in 256mb DDR3 image buffer to remove amp glow and other artifacts caused by data transfer over USB2, all while preventing issues with dropped frames. This makes for a seamless and fast imaging experience, whether you're taking advantage of the flexibility and low cable weight of USB2, or the fast speeds of USB3.

Our experience of working with demanding scientific applications has given us an advanced understanding of sealing techniques. This understanding allows us to create a condensation free environment, and means your desiccant lasts much longer between recharges. We're using the same quartz fused cover glass as our Atik 383L+ camera to prevent condensation forming on the outside of the glass when the camera's cooled. This added level of performance and reliability means you can spend less time maintaining your equipment, and more time imaging with it.
