Astrophotography: New cameras from ZWO

May 30 2016, Stefan Taube

The cameras from ZWO, which can be recognized by their distinct red housing, have taken astrophotography by assault. Based on the big success of the low-priced planet cameras ASI-120, ZWO now extends its product range bit by bit and now also offers advanced cameras with USB 3.0 and CMOS-sensors.

We are able to offer you two new series of these cameras:

ZWO Camera ASI

ZWO Camera ASI

  • ASI-290: A very good all-purpose camera with small pixels, high image frequency and low read-out noise. The camera is equipped with the CMOS-sensor IMX290 from Sony. This chip is particularly light-sensitive because it is exposed from the back. Such sensors are elaborate in production, but now they are available to hobby astronomers for a reasonable price.
  • ASI-1600: This camera is equipped with a huge 16 megapixle CMOS-sensor with 21.9 millimetre diagonal. The sensor is normally installed in Olympus cameras. With this camera you can fill a large field of view.

All camera models are available as colour or black and white variants, but also with or without active cooling. I.e. there are four versions each for you to choose from.

Black and white cameras have the advantage of a higher sensitivity and resolution when compared with colour cameras. However, it takes a higher effort to successfully shoot colour images: You need colour filters and a fllter wheel.

A cooled camera allows for longer exposure times, because the sensor noise is suppressed. However, you need a separate electric power supply and, for long exposure times, a suitable mount with tracking control. Due to the increasingly high sensitivity of the sensors, uncooled cameras also become more and more popular for the photography of low-luminosity DeepSky objects. Beginners and casual photographers are therefore already very well equipped with the uncooled models of the ASI-290 series.
