Thanks Guys.
Asi, yeh I'm a bit surprised too at the detail that can be extracted now from Mars given it's area is now down to 1/5th of what it was at opposition. I'm thinking to some extent it must a bit like when you draw on a balloon and blow it up that the features get bigger but fainter - so in reverse as Mars shrinks the fine detail dissapears but the macro detail actual gets more contrasty and easier to see and image
Anyway, I'm very happy with these - anothery to add to the Mars death cycle image
cheers,
