Every day our eyes catch the light of our memories – time spent with family, the journey to work, a special holiday, a beautiful sunset or a dark starlit night. Each image captured is a picture drawn in light – a photograph: only to be lost in our minds or forever forgotten. Nearly two hundred years ago a small group of amateur scientists achieved what had eluded mankind for centuries – the ability to capture a permanent record of an image seen by their own eyes – a moment in time frozen onto a surface. They had discovered Photography. They were the ‘Catchers of the Light’.

Emission line data Moon



Pseudo RGB attempt, from emmision data Ha and OIII with synthetic Blue.
Red=Ha_ Green=OIII_ Blue= 33%Ha+67%OIII

too many "lies"...in one image, but the result is quite similar to RGB.
