Manufacturer's product description:

Monochrome USB Astronomy Camera with 60 fps for Astrophotography

Up to 60 frames per second
With 60 fps, the monochrome astronomy camera DMK 21AU04.AS is the fastest within its category. 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 astro CCD camera DMK 21AU04.AS uses the monochrome progressive scan CCD ICX098BL 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 use in industrial image processing applications.

No compression, no filter
The CCD camera DMK 21AU4.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 21AU04.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.

Shipped software for Windows
This camera ships with the camera driver and the control software IC Capture.AS.
