With up to 60 fps, this astro CCD camera is ideally suited to color astrophotography, in which very fast sequences of images are captured. Using the shipped software - IC Capture.AS - you can capture lossless and uncompressed images sequences as AVI files. The telescope camera DFK 21AF04.AS generates a fast stream of uncompressed color 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.
IC Capture.AS performs color interpolation on the raw color data (RAW format) from the CCD chip. This reduces the load on the camera processor. Should, on the other hand, the camera be installed on a host PC in which the CPU is not particularly fast, color interpolation can be performed by the camera itself. In this case, the maximum refresh rate is 30 fps. Alternatively, should color interpolation not be desirable at all, AVI files can be written in RAW format.
The telescope camera DFK 21AF04.AS uses a modern color CCD chip (ICX098BQ, progressive scan, manufactured by Sony). It outputs a resolution of 640 x 480 pixel at a 1/4" format. Even at long exposure times, its noise is minimal. The high quality of the CCD chip also permits its deployment in scientific image processing applications. The CCD camera DFK 21AF04.AS is equipped with an IR cut filter that blocks wavelengths above 700nm. Thus, its properties are similar to those of the human eye.
