About this product

Model:  atik_horizon_mono
Part Number:  ATK0156

New Atik Horizon II due soon - prices and info to follow.

Atik's first CMOS imaging camera smiley

The Atik Horizon is a beautifully made camera with a sensitive 16MP 4/3" Panasonic CMOS sensor that delivers exceptionally low read noise and incredibly fast read speeds - at a competitive price!

An excellent choice if you’re upgrading from DSLR or have a system that would benefit from shorter exposure times. 

The Horizon has the lowest read noise of any Atik camera. Only ~1e- at high gain settings!

The 3.8µm pixel size is an excellent match for shorter focal length telescopes and camera lenses - excellent news if you’re looking for a wide field of view.

Mechanically, the Horizon is based on Atik's established 4-Series cameras, known for their power and adaptability. The cylindrical case measures 74mm in diameter (130mm length) so is compatible with HyperStar systems from 8″. The slightly larger size (compared to other 4-Series) has enabled a larger cooler with a 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 Horizon is natively compatible with Atik's Infinity live stacking software for near real-time views of the night sky. A great choice for video astronomy and public outreach, it also makes getting into astrophotography a breeze. On-the-fly image processing gets you up and running quickly, minimising the learning curve many people experience. And 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 is also fully compatible with Atik's Artemis Capture imaging software that provides full control over your imaging. Atik also supply a full ASCOM driver so you’re free to use it with your preferred astroimaging software.

Amp Glow Control

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

Our experience with demanding scientific applications has given them an impressive understanding of sealing techniques. The Horizon features a condensation free sensor chamber (desiccant tablets last much longer between recharges) with the same quartz fused cover glass as used in their Atik 383L+ camera to prevent condensation forming on the outside of the glass when the camera has cooled. Spend less time maintaining your camera, and more time imaging with it!
