Ziz- Although that doesn't satisfy me I'm afraid, it's certainly another way of looking at it, and Ady may agree with you.
The second 'Probe' crash that Luke watches on his Tauntaun is a far better-looking object entry (longer, lighter streak effect ) than the initial bright pink 'blob' that crashes into Hoth. The shot just before the 'pink blob' shows the 'casing' of the Imperial Probe Droid heat up as it enters the Hoth atmosphere, then darken. I think the charred 'casing' crashing into the snow instead of a 'pink blob' would look far better, or at least would be better if it at least looked more like the one Luke watches.
