  • Resolution 640 x 480
  • Max. 60 fps
  • Max exposure time 60 min
  • C/CS Mount

Up to 60 colour frame per second

The astronomy camera DFK 21AU618.AS outputs up to 60 colour images per second. It is therefore ideally suited to methods in astrophotography that require high frame rates. Using the shipped software - IC Capture.AS - you can capture lossless and uncompressed images sequences as AVI files.

Fast display of colour images

IC Capture.AS performs colour interpolation on the raw colour data (RAW format) from the CCD chip. This reduces the load on the camera processor. Should, on the other hand, the camera be installed on a host PC in which the CPU is not particularly fast, colour interpolation can be performed by the camera itself. In this case, the maximum refresh rate is 30 fps. Alternatively, should colour interpolation not be desirable at all, AVI files can be written in RAW format.

Sony colour CCD

The camera DFK 21AU618.AS uses the near infrared, extremely sensitive CCD ICX618AQA from Sony. It outputs a resolution of 640 x 480 pixel at a 1/4" format. Even at long exposure times, its noise is minimal. The high quality of the Sony® ICX618AQA also permits its deployment in scientific image processing applications.

IR Cut Filter

The CCD camera DFK 21AU618.AS is equipped with an IR cut filter that blocks wavelengths above 700nm. Thus, its properties are similar to those of the human eye.

Fast data transfer via USB 2.0

The astronomy camera DFK 21AU618.AS generates a high rate of uncompressed, monochrome images. In order to transfer these to the host PC, a very fast bus is required. Hence, the camera is fitted with a USB 2.0 connector.

NB: Some USB controllers built into PCs might not be able to handle the data rate required for 60 FPS. If you have USB3 (USB3 is better even in USB2-mode) you should not experience a problem. The same might be true of some Firewire connections but we don't have enough feedback yet to comment.
