Hi All,
I have been browsing through Astrobin and came across
this image. It is an amazing image but what is interesting is the exposure time. Romain uses lucky imaging to capture heaps of detail in the galaxy using 1-second exposures.
Why would only 1-second images be used? I understand that the camera is probably highly sensitive, and has very low noise, but how would he get away with this much detail in such short exposures with very low noise? Do the 1-second exposures somehow negate a lot of atmospheric distortion? Again I'm astounded by the amount of detail that he has got out of it and how bright it is.
Thanks!
