After years gone by hunting things visually, I still get a real kick out a seeing single 5min sub showing more detail than I could EVER hope to see with a remotely affordable visual rig.
There's definitely no harm in running the sums on focal ratio, spectrum sensitivity, FOV etc. I suspect an ED80 and DSLR will be about 10 times cheaper than the 12" F3.8 CCD rig too though!?
