I just made a comparison bewteen what a 30min exposure got me back in 1984 compared to what 30min (10min each R G B) gets me today
Orion Nebula 1984 V 2011
That B&W photo was very exciting in 1984 and was even part of an award winning display....funny how things improve, man if someone had shown me my 2011 version back in 1984 I would have fallen of my chair
Also put up the
Luminance only version of the latest data
