ZWO ASI174MM 2.3 MP CMOS Monochrome Astronomy Camera with USB 3.0 # ASI174MM

The ZWO ASI174MM is a sensitive and state-of-the-art monochrome 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. It's ideal for high-resolution imaging of the Moon, Sun (with proper solar filter), and planets, as well as brighter deep-sky objects.

The heart of this monochrome 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.

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 300 s (5 minutes).

The ASI174MM has a robust and attractive CNC machined red-anodized aluminum body that stands up to heavy field use. An AR-coated glass window protects the sensor and helps keep images sharp. A 1/4-20 thread in the bottom of the camera makes it easy to attach the device to a camera tripod or mount, and four M4 threads along the outside edge offer additional mounting options.

The camera body features a standard T/T2 female thread (M42x0.75) so that it can be directly connected to T-threaded accessories. Included is a 1.25"-T threaded nosepiece adapter that allows you to use the camera in standard 1.25" telescope focusers. The front of the camera also has a short (11mm long) 2" barrel that can be directly inserted into 2" telescope focusers. However, we recommend that use of a 2" T threaded prime focus adapter (not included) for a more robust connection to 2" telescope focusers.

The ZWO ASI174MM astronomy camera can be used on 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.
