Problems with Hubble Imax

Hubble is 3D in sense of depth, not roundness.

tFlat objects are separated from each other by depth, but there is no 3D for each object. The video footage has been left with a grain & wash-out that could have been improved. The long starfield sections appear to be computer generated.
Much of the imagery could have been shot two decades ago
and then adjusted in a computerto look like the current movie. They could have done much better.
