In November 1999 I purchased a used CCD camera made by OES Fleischmann. This LcCCD07 is the smallest camera with a resolution of only 195*165 pixel and uses the Texas Instruments TC211 chip. It is single stage peltier element cooled and offers integration times ranging from 0.6 up to 40 seconds. The camera comes with a ISA 16-bit PC card as driver and offers relay control for autotracking.
In January 2001, after the camera returned from a *repair* from OES, I added a small potentiometer, which allows me to adjust the bias offset, which tends to drift a little while the camera gets warmer.
April 2001: Long exposure images show some moiree, and I have to investigate, where this noise comes from. A possible source may be some RF influence by the clocked signal wires close to the offset potentiometer I added. I'll have to possibly use shielded wires and block the lines.
I received the complete circuit diagram from OES, which makes me understand better, what happens inside the camera head.
There was not much time for using the camera so far, as it was defective for quite a while. Now I look forward to produce some images. I spent this time with reading a lot of literature and I hopefully know now what the camera may be good for.

The field of view with my Newton f5 / d=150mm is 12.1' (12.1 arcmin). Many objects in the sky will not fit into the image.
