Janie, your Hubble description is as good as any I could come up with. Let's go with that one.
There are no Hubble images in the series.
Only 6 images are photos by astronauts, the rest are computerized representations.
I don't want to get too hair-splitty, but Hubble's images are recorded across a broad part of the light spectrum; from UV to Infra-Red. Frequencies of light can be chosen and combined to form images which reveal the chemistry and physics of astronomical objects.
Certainly the increased use of image processing is improving our understanding of astronomy.
