640 x 480 resolution with enhanced-sensitivity Sony EXview HAD sensor
Up to 60 frames per second
With 60 fps, the monochrome astronomy camera DMK 21AU618.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 DMK 21AU618.AS ships with the monochrome Sony ICX618ALA 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 ICX618ALA CCD chip is also often used in other scientific, industrial and medical image processing applications.
No compression, no filter
The DMK 21AU618.AS does not compress the video stream it outputs - the video data that is captured by the CCD chip is outputted directly by the USB connector. Similarly, the camera does not have an IR cut filter, a color filter, nor an other kind of electronic filter. The camera is, therefore, ideally suited to capturing very true-to-life images of the night sky.
Fast data transfer via USB 2.0
In order to transfer the vast amount of data created by the stream of uncompressed and lossless monochrome images to the host PC, you need a very high speed bus. Hence, the DMK 21AU618.AS is fitted with a fast USB connector.
The DMK 21AU618.AS ships with the device driver IC WDM UVCCAM TIS and the camera control and image acquisition application IC Capture.AS. Both of these run on Windows XP, Windows Vista and Windows 7 (32 and 64 bit).
