Very neat trick, J. I wish I had thought of that!
Conversely, stacking the frames brings out subtle details in the shorelines of the lakes and within the bright evaporite: -------------------- |

Processing my own astrophotography falls, usually, into one of two modes: Deep sky objects, with incredible detail that is usually very subtle, and planetary objects, where the effects of the Earth's atmosphere is the major obstacle. In my version, Ian, and yours, we basically tackled this data set in those two ways. I used the median-subtraction to bring out faint details, and you used image stacking to compensate for the blurring effects of the atmosphere (in this case, Titan's).
This is basically a 3-D dataset, so there are many ways to rework it. Perhaps we've barely scratched the surface. |
