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’.

Triangulum Galaxy M33 I love it !!!

This is an image with the same old data from Nov 2013 but with a new approach about processing .
I made a synthetic luminance layer from the whole of my frames. Then I apply about 30 iterations of selective deconvolution in ccdstack. With ''selective'' i mean: manual selection of the area for deconvolution.
And the question is :What is the exposure time in this image ?
the total exposure time is the sum of whole frames and that is or the sum of the separate master layers such as Lum LumSynth RedSynth(Red+Ha) and so on

Instruments and exposure data:

Lum :147*5min bin1x1 (12h 15min)
Red :35*6min bin 1x1(3h 30min)
Green :27*6min (2h 42min)
Blue:46*6min bin1x1(4h 36min)
Ha:23*10min bin1x1(3h 50min)

Total exposure time 26hours 53min
