Hallo John,

Yes, it is the Celestron 8". They have also rebuilt their 10" Schmidtcameras
which
used 6 x 6 film and all without field flattener.

They didn't flattened the field because it is not necessary due to Philipp
Keller who
built the 10" cameras.

They have rebuilt 2 or 3 Schmidtcameras into CCD.  I hope they can provide me
some images how the camera looks like with the ccd-camera
built in.
