The problem with sprites nebulae in Celestia 1.6.1 is that they are still rendered as a very luminous pixel while you are standing very very far away from the model. The sprites do not fade away with distance. The special Celestia 1.7.0 for OS X that I published elsewhere on this forum had fixed this important bug.

Code: Select all
Color [1 0.85 0.75]
Right part of the picture is the same texture, inverted, with a bit more contrast and same color blending :
