About Imaging Source

With 60 fps, the monochrome telescope camera DMK 21AF04.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. The telescope camera DMK 21AF04.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 FireWire connector.

The astro CCD camera DMK 21AF04.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 used in industrial image processing applications. The CCD camera DMK 21AF04.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.
