We've added 12 hours total of 2x2 binned RGB to our previous 10 hrs unbinned monochrome shot. Pleasingly similar to Shiraz's recent LRGB photo.
Full size image here.
Things to see:
- A near face-on barred spiral. The centre is neither very bright nor very orange. Indeed, a very blue galaxy given it doesn't seem to be tidally disrupted. Wikipedia reports ESO studies showing it is probably gravitationally bound to NGC 55, which is fiercely distorted and even more blue.
- Lots of tiny pinprick blue dots marking out the otherwise faint spiral arms.
The larger blue dots are presumably OB associations of hot young stars. Some of the tiny ones may conceivably be individual stars.
- Half a dozen or so conspicuous red rings [HII regions] similar to those seen in Barnard's Galaxy. Can't wait to try photographing these in H-alpha.
- A seahorse-shaped tidally disrupted galaxy with a vertical tidal tail at about ten o'clock and 2/3 of the way out from the centre.
- Squillions of background galaxies, many edge-on spirals, many red ellipticals, some in distinct clusters.
