Congrats for the article.
I have a doubt and honestly i always try to get some explanation when i talk about my doubt without getting any good answer. I understand that the multiple exposures are to avoid noise reduction right? Cause the heat of the sensor, static electricity etc. So can you tell me what is the difference between an 5 hours exposure and a 5x10 min exposures? How can you cool down the sensor by doing a multi exposure technique? how can the sensor cool down on a matter of seconds? and even the noise reduction of the camera is OFF avoiding the waiting to process the image.
