The problem with the whole Respecting the Light concept is it solely depends on the camera and telescope being used as to what is "respect". I can buy a scientific camera with a read noise of 1.7e- ultimately allowing read noise limited exposures of 45 seconds in narrowband, plus it has 120k well depths.

Now I can either do a single 60min exposure with the KAF8300 with 25k well depths or many shorter exposures and pick up no detail but also not blow out the brighter regions.
OR
With the correct camera I can take 80x60s exposures, be read noise limited and have an enormous dynamic range. It can also take a 60min exposure without blowing out the highlights.

So, what really is Respecting the Light?
