Colin you are quite correct.
Our senses are limited by their physical reality. For example colour does not exist! It is merely the ratio of three different sensing molecules in your eye's cones that are sensitive to different wavelengths that enable the brain to synthesise the sensation of colour.
Other species have up to and more than five 'colour' receptors.
Your brain is a superb computer working in real time to extract all the available information of what you see. From the very dim scene of the proverbial black cat in a coal mine to the bright Sun drenched savanna. The large bit at the back of your head contains the very large part of your brain that does this processing in real time. The conjecture is that even Fourier enhancement is going on in real time as the resolving power of your eyes lens and photoreceptors is far poorer than what you sense.
Modern digital cameras have an advantage our eyesight does not, and that is a long integration time. This of course loses temporal information. Our eyes and brain are exquisitely tuned for the slightest movement. It is this difference that has evolved over many millions of years between having a dinner and being dinner!
Our visual senses have also evolved with a limited spectral sensitivity as our atmosphere blocks both short and long wavelengths.
Stars and thus galaxies etc emit a far larger range of EM radiation and high energy particles. That is why one mob of smart apes on a tiny third rock from a nondescript star are still inventing better detectors than their eyes.
How to present this data is matter for argument amongst ourselves. There is no 'correct' method. Just specify the conditions.
