I enjoyed looking at this one, but with that kind of investment in imaging gear, invest an extra tiny percentage of that into one of these:

It is a pittance compared to the spend on camera/filters/scopes etc. but without it, we may as well have cheapo filters as we aren't getting the best out of our imaging. It can also calibrate your TV/projector etc.
For those on a budget, grab one of these,

they can often be found for under a hundred.
Without monitor calibration, imaging processing is a somewhat random exercise. I reckon a colourimeter should be the first purchase after you buy a camera. People spend so much chasing optical perfection, it's worth spending a tiny bit more to make sure you are seeing the results of all that work in their true colours.
