Product Details

The ZWO ASI178MM is a sensitive and state-of-the-art monochrome astronomy camera with 6.4 megapixel resolution and USB 3.0 download speed. Built around the Sony IMX178 back-illuminated sensor, this advanced camera has a resolution of 3096x2080 with 2.4 μm pixel size. With 14-bit ADC and low read noise, this high-sensitivity camera is ideal for high-resolution astronomical imaging and works well for microscopy imaging as well.

The heart of this monochrome camera is a Type 1/1.8 CMOS sensor with 8.92 mm diagonal. This advanced sensor incorporates Sony's Exmor R technology that enables high-speed processing, low noise, and low power dissipation using column parallel A/D conversion with the back-illuminated sensor. The sensor also incorporates Sony's STARVIS technology features a sensitivity of 2000 mV or more per 1 µm2 and allows high image quality in the visible-light and near infrared light regions.

The 14-bit ADC enables high dynamic range and reduced quantization noise and dark random noise. This makes for clearer image quality in light and dark areas when imaging objects with high contrast.

The rolling shutter and fast USB 3.0 interface on the camera allow transfer rates of up to 60 frames per second at full 3096x2080 resolution. At reduced resolution of 640x480, download rates up to 253 fps become possible. The camera enables exposure times of 32 μs to 1000 s (16.7 minutes).

The ASI178MM 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. 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.

This camera can be configured with the following connections for attachment to telescopes and imaging accessories:

  • 1.25” nosepiece
  • 2” nosepiece (optional 2” extension strongly recommended)
  • Female T/T2 thread (M42x0.75)
  • Female C/CS thread (1”x32TPI)
  • Female M28.5x0.6 thread

The ZWO ASI178MM astronomy camera can be used with just about any telescope. 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. A 2.5mm all-sky lens is also included to give a 170° all-sky view when threaded into the camera. When used for autoguiding, the camera can also work with Maxim DL or PHD when guiding with long exposures.

ZWO is phasing out software CDs, but the camera comes with instructions to help you download the required control software and drivers directly from the ZWO website.
