Begging the question: does the theory matter that much given the practical applications of many astro-imagers? |
none of this has the slightest bit to do with CCD QE Peter.
- Seeing will remain the same regardless of which chip you have and the high QE chips will still be twice as fast in good seeing as in bad
- the 3200 is a great science chip, but it has 3mpixels and it blooms - it is not a pretty pictures chip
- the theory is very well developed in professional circles and underpins all that we do, whether we know it or not. You might not like the implications, but the theory is a very accurate and complete representation of reality. It would be foolhardy to ignore it.
