I have done countless space and astronomical pictures, usually in "editions" and series which I took to conventions and sold at low prices. I was inspired by the space art of those days, which was itself inspired by ground-based telescopes yielding blurry, poorly detailed images. This was, most importantly, pre-Hubble.
Looking back at my thirty years of space art, sprayed on with an airbrush, I can see that it, like other space art of its day, is out of date. Once the space telescopes went up, and once the "adaptive optics" of ground-based telescopes were deployed, as well as digital photography, you got the most amazing fields of details never before seen. With all those almost biomorphic clouds of dust and gas, illuminated by bright young stars, who needed my old airbrush?
Interestingly, my more abstract, "graphic"-looking space pieces survived better artistically. This one, a simplified dwarf planet or moon above a nebula, resembles some of the images of Saturn and its moons produced by the Cassini space probe. Artists are still producing space pictures, making realities out of digital information rather than acrylic paint.
