ZWO ASI1600MM-Pro
The ASI1600 was the first dedicated astrocamera in use at the observatory. This camera has been used by many astrophotographers around the world and comes in different versions. At the heart of all is a Micro-Four-Thirds CMOS sensor from Panasonic. This is the same sensor found in for example the Panasonic GH-4 camera, but without the colour-filter array. It has a resolution of 16MP and a pixel-size of 3.8 µm.
Being a Pro-version it has cooling built in. The sensor can be cooled down to about 40 ºC below temperature. The camera is monochrome, so filters are required to make color images. See below for more details on filters and filter wheel.
The camera downloads data through a USB-3 connection and acts as a USB-2 hub for the filterwheel. Power for the cooling is applied through a 12V DC connection.
Compared to modern sensors, the ASI1600MM shows its age. It is mostly replaced by more modern cameras such as the ASI533MM and ASI6200MM and not in active use anymore in the observatory.
