About this product

Model:  DFK_21AU04.AS_Colour

USB 2.0 Colour Camera with 60 fps for CCD Astronomy.

  • Colour USB camera with IR cut filter
  • 1/4" CCD, progressive scan
  • Resolution 640 x 480
  • Max. 60 fps
  • Max exposure time 60 min
  • C/CS Mount
Up to 60 color frame per second

With up to 60 fps, this astro CCD cameras is ideally suited to colour astrophotography, in which very fast sequences of images are captured. 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 color interpolation on the raw color 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, color interpolation can be performed by the camera itself. In this case, the maximum refresh rate is 30 fps. Alternatively, should color interpolation not be desirable at all, AVI files can be written in RAW format.

Sony colour CCD

The astronomy camera DFK 21AU04.AS uses a modern colour CCD chip (ICX098BQ, progressive scan, manufactured by 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 CCD chip also permits its deployment in scientific image processing applications.

IR cut filter

The CCD camera DFK 21AU04.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 21AU04.AS generates a fast stream of uncompressed colour 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.
