About the Imaging Source DFK 21AU618.AS

The Imaging Source DFK 21AU618.AS Color USB Astronomy Camera is ideally suited to color astrophotography, in which very fast image sequences should be captured. The camera ships with IC Capture.AS, a comprehensive software package with which you can capture lossless and uncompressed images sequences and write them to disk as AVI files, or as a series of singular bitmaps.

The DFK 21AU618.AS ships with the color Sony ICX618AQA progressive scan CCD chip. With its 1/4" format, the CCD chip produces a resolution of 640 x 480 pixels. Even at very long exposure times - up to 60 minutes exposure are possible - noise is minimal. Thanks to this extremely high quality, the Sony ICX618AQA CCD chip is also often used in other scientific, industrial and medical image processing applications.

  • Software Bundle
  • The Imaging Source Warranty

Imaging Source DFK 21AU618.AS Features

  • Color Interpolation: For visualization applications, it does not make sense to view the RAW image stream from the CCD chip. It must be interpolated, before it may be viewed or saved in common formats. IC Capture.AS perform color interpolation, thus reducing the load on the DFK 21AU618.AS's processor
  • IR Cut Filter As Standard: Unlike the human eye, CCD chips are sensitive to near infrared light (wavelengths over 700 nm). The DFK 21AU618.AS ships with an IR cut filter as standard and is thus suited to applications in which these wavelengths would lead to interference or undesirable results
  • High Speed Data Transfer Via USB: In order to transfer the vast amount of data created by the stream of uncompressed and lossless color images to the host PC, you need a very high speed bus. Hence, the DFK 21AU618.AS is fitted with a fast USB connector
