Up to 60 frames per second
The astronomy camera DMK 21AU618.AS outputs up to 60 monochrome images per second. It is therefore ideally suited to methods in astrophotography that require high frame rates. It is ideally suited to black and white astrophotography, in which very fast image sequences are captured. Using the shipped software - IC Capture.AS - you can capture lossless and uncompressed images sequences as AVI files.
Monochrome Sony CCD
The camera DMK 21AU618.AS uses the near infrared, extremely sensitive CCD ICX618ALA from Sony. With its 1/4" format, the CCD produces a resolution of 640 x 480 pixels. Even at long exposure times, its noise is minimal. Thanks to its unsurpassed quality, the ICX098BL is often used in industrial image processing applications.
No compression, no filter
The CCD camera DMK 21AU618.AS does not use compression, nor does it have an IR cut filter, a color filter or an electronic filter. Thus, the camera produces very true-to-life captures of the night sky.
Fast data transfer via USB 2.0
The astronomy camera DMK 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.

Our expert comment:
Device driver for The Imaging Source cameras (also for Windows 7) can be found here: Device driver for The Imaging Source cameras
The new 618 cameras with CX618 chip are much more sensitive than the previous ICX098BQ DMK chip and have twice as high a full frame rate.
The new chips from the Sony ICX618 ALA series provide:
- 50% more sensitivity in the blue
- 100% more sensitivity in the green
- and
- 200% more sensitivity in the red
than the previous DMK models with the older ICX098 and ICX204/205 chips. The shorter exposure times make it even more efficient to 'freeze' the seeing and making better use of the higher 60fps frame rate.
