That's awesome Rick
thanks so much for taking the time out to analyse the data.
The old CCD, hereon known as "ol' faithful"
really does walk away from the DSLRs. Cooling the DSLRs would make for some more interesting data points.

Wow, yeah not only is there a clear difference between the DSLRs, but the CCD still shows its mettle
