Fred, that's a superb shot. The "? PN ?" is a mixture of Herbig-Haro objects (especially the bright red blob) and their associated collimated jets, emitted by the (infrared and therefore invisible) infant protostar R coronae Australis. You've actually got some fine detail on the main collimated jet - very sharp indeed. Super-inky-black dust there too. Excellent.
