Open Box ZWO ASI 294 Pro Cooled Color CMOS Camera - UT-12599 -SOLD-

The ZWO ASI 294 Pro has set a new standard of Excellence in the world of Astrophotography. Whether you are interested in deep space astrophotography or Lunar/Planetary/solar Imaging, this camera will be able to handle it all. There are not many camera systems that can do what ASI 294 can do.

At the Heart of the ZWO ASI 294 is the Sony IMX294 CMOS Sensor which is known for its exceptional light gathering efficiency, low read noise, and High resolution. The sensor will record up to 11-megapixel images on a Micro 4/3rds format. The camera has a dynamic range of 9 to 13 stops depending on gain settings. Read noise levels can be adjust between 1.2 and 7.3 electrons, and if you set the gain to 120 DB you can get almost the full 13 stops dynamic range with a read noise of 1.7 electrons!

The ASI 294 works very well as a deep-space camera. Cooled versions will reach temperatures 35-degrees Centigrade below the ambient temperature bringing thermal noise buildup down to a minimum. You can take pictures up to 33 minutes with this camera, however, with such low noise images exposures that long are rarely necessary. When shooting deep space images at full resolution this camera pairs very exceptionally well with telescopes 300 mm to 1,300 mm in focal length.

As a planetary camera, no other camera system can beat the ASI 294's versatility. For solar imaging, this camera can record full 11 mp videos at 19 frames per second and capture the entire sun with 1350 mm focal length!
