This design is clearly a new flat field Schmidt design optimised for the new breed of larger format cameras. It has longer fl primary than the typical sct (which is around f 1.5), so it is not just an add on to existing sct optical components as the FASTAR was. Anything that Dave Rowe, desighner of the CDK, is involved in should be pretty state of the art. Celestron technological know- how is still based in a tight US team, and the optical quality I have seen in chinese made SCT has been excellent, so assuming that the instrument is of sound mechanical design it should be a winner. The challenge will be maintaining focus as the depth of focus would be small.
Im not an imager but I would say this is an exciting development for those wanting to cover large fields deeply.
