Photography of "far away things" - space, but I may also want to include anything in our atmosphere or just nice landscape shots.
Looking at this image: http://hyperphysics.phy-astr.gsu.edu/hbase/astro/quasar.html the lensed images of the galaxy are all blue so it looks like a side-effect of the lensing.
A double quasar... Whatever next! I can't work out why it is blue.
