Product Details

The ZWO ASI174MC-COOL is a sensitive and state-of-the-art color astronomy camera with 2.35 megapixel resolution and USB 3.0 download speed. Built around the Sony IMX174 sensor, this advanced camera has a resolution of 1936x1216 with 5.86 μm pixel size. With regulated two-stage TEC cooling, this camera can cool the sensor to 35C to 40C below ambient to keep noise low. It's ideal for high-resolution color imaging of the Moon, Sun (with proper solar filter), planets, and deep-sky objects.

The heart of this color astronomy camera is a Type 1/1.2 CMOS sensor with 13.4 mm diagonal. With a quantum efficiency (QE) of 78%, this advanced sensor incorporates Sony's Exmor technology that enables high-speed processing, low noise, and low power dissipation using column parallel A/D conversion.

The IMX174 sensor also uses Sony's Pregius Global Shutter function with analog memory to permit the scanning of all pixels simultaneously. This improves image quality by ensuring images of moving objects avoid focal plane distortion, a feature which is especially helpful when performing solar or lunar imaging during moments of wind and bad seeing.

On the camera body, next to the USB3.0 and guide ports, a 2.1mm center-positive connector provides an input for the cooler power supply (not included). From the supply, the camera requires 12VDC @ 2A maximum. A Cooler Power LED shows when the cooler has sufficient power. There's also a large built-in heat sink which accounts for nearly 2/3 of the camera's size. At the top of the camera, an advanced and efficient MagLev fan removes heat from the TEC and control electronics while keeping acoustic noise low.

The sensor shutter technology and fast USB 3.0 interface on the camera allow transfer rates of up to 164 frames per second at full 1936x1216 resolution. At reduced resolution of 640x480, download rates up to 397 fps become possible. Using the sensor's ROI (Region of Interest) mode, which lets you capture up to 16 areas inside the effective pixels, even higher frame rates are possible. The camera enables exposure times of 32 μs to 1000 s (16.7 minutes).

The ASI174MC-COOL has a robust and attractive CNC machined red-anodized aluminum body that stands up to heavy field use. An AR/IR-CUT glass window protects the sensor and helps keep images sharp. The camera body includes a standard 2" M42x0.75 internal thread interface on top for adapters, and a 1/4-20 thread in the bottom to make it easy to attach the device to a camera tripod or mount.

The ZWO ASI174MC-COOL color astronomy camera can be used with just about any telescope. It comes with everything you need to get started including a CD with user manual, Windows camera driver, ASCOM driver, SharpCap Image Capturing software, FireCapture Image Capturing software, and Stakkert 2 Stacking software. You also get a 2-meter USB 3.0 cable and a 2-meter ST4 guider cable for use in autoguiding. A M42-threaded 1.25" nosepiece, and a 1.25" cover also come with the camera. When used for autoguiding, the camera can also work with Maxim DL or PHD when guiding with long exposures.
