NGC 6935 and NGC 6937: a pair of beautiful, presumably interacting pseudo-ringed spiral galaxies in Indus.
Please see uncropped full size image here.
NGC 6937 is bluer, has four spiral arms in a twisty tangle like a drunken starfish perhaps, with many bright blue splotches of recent star formation.
NGC 6935 has less star formation and is more salmon coloured. It looks like a very tightly wound Catherine Wheel, with an inner pseudo-ring that looks like a rounded-cornered square - most unusual. Not often photographed. (Mike Sidonio did a good one.)
We like the star field, which (in the uncropped image) contains many brilliantly coloured jewels. There are also at least 85 easily identifiable background galaxies, many of which are edge-on spirals, their shape shown by the sharp winter skies.
