The ASI071 features an APS-C sized imaging sensor. It uses the same 16MP imaging sensor as the Nikon D7000/7100 and D5100. The big difference is that the electronics were designed specifically for deep sky imaging and the camera also includes two-stage TEC-cooling. The ASI071 is only available as a colour version.
Colour cameras have real benefits over mono counterparts. The most obvious is the reduced cost as you do not have to invest in a filter wheel or filters. The real benefit is that you only have to take a third or even a quarter of the images you would take with a mono camera. When imaging time becomes limited due to poor skies this becomes an invaluable time saver.
The ASI071 also provides a video function and can run as high as 10FPS at maximum resolution. This offers the possibility to use it as a real time live view camera thanks to advances in capture applications such as SharpCap. This versatility also permits capture of objects like the moon like a traditional high frame rate camera. Multiple exposures can then be stacked for an extremely low noise result
The ASI071 also includes some other useful features. Although it requires 12v DC power to operate the cooling system, if you do not wish to use this then the camera is easily powered via USB 3.0 only. The camera also features a USB 3.0 hub permitting a single USB cable to connect both the camera and another device like a guide camera. When being cooled to very low temperatures, there is a real risk that the window covering the sensor can fog up. To avoid this the ASI071 has integrated chamber warming. At the front of the camera is an integrated tilt adjuster. This can be very useful if you find your focuser suffers from tilt.
