DeepSky-Set: Cooled camera ASI 1600 with filter and filter wheel from ZWO

March 13 2017, Stefan Taube

ASI 1600 MM series cameras from ZWOptical have really found their place in astrophotography. With its small pixels, the highly sensitive CMOS sensor offers high resolution, and this even in connection with a relatively big sensor diameter.

We now offer the cooled black and white camera of the ASI 1600 series in a set with a motorized filter wheel and suitable filters: ASI 1600 MMC DeepSky-Imaging-Set for a price of 2,019 Euro. You save 29 Euro when compared with individual prices!

A camera with active cooling is optimal for taking photos of nebulae and galaxies, because the cooling reduces sensor noise and thus enables long exposure times. This enables you to even take photos of very faint objects in the sky.

Even though the cooled ASI 1600 is available as colour or black and white camera, only the black and white camera offers the full resolution of the sensor. Ambitious photographers therefore favour this variant. In order to show the colour of the celestial object you just simply take photos through three colour and one luminance filters – the latter to increase brightness. The computer then uses these four images to produce a colour image (L-RGB method).

The filters are placed into a filter wheel, so that the camera does not have to be removed and realigned again for each filter change. The filter change simply takes place by turning the wheel. The filter wheel in the Set with the ASI 1600 is electrically powered and controlled via the camera, meaning you do not need an additional cable connecting to your computer. You simply use the camera control to change from one filter to the next, and this, above all, without having to touch anything.

The four filters in the DeepSky-Imaging-Set were specially developed for the ASI 1600. The colour weighting has been optimized for its sensor, which in this case is a high-quality interferential filter. Since the filters are parfocal to one another, the focus position does not change when changing the filter. Besides the three filters for the red, green and blue channel, the set also contains an UV/IR band-rejection filter for luminance.

Just as the graph concerning the filter transparency (transmission) of the set indicates, the filters block out the disturbing light of many street lamps, but are highly sensitive in the red range of the H-Alpha and SII-line. The transmission rate is greater than 92%.

With the ASI 1600 MMC DeepSky-Imaging-Set you receive a high-quality, yet reasonable, camera system with almost unlimited possibilities!

 

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.
