I don't understand the quest for red that most imagers have. The results
from Da's and modded DSLRs are, it would seem, false representations
of DSOs, because they overwhelm the blues and greens that are present,
whilst unmodded ones are also false because they show little red.
A good example is Traveller's post of M20. 35 mins exposure time, and only the faintest trace of blue. Ordinary DSLRs, it would seem are
insufficiently sensitive to red, but moddeds are at the other extreme.
Is it not possible to produce a camera with a greater range of colour
sensitivity.
