The Flying Bat (Sh2-129) and the Squid (Ou 4) Nebulae. These relatively faint Nebulae are located within Cepheus, a neighbour of the larger often imaged IC 1396. The Squid is a recent discovery, being first observed in 2011 by French astronomer Nicolas Outters. The Squid is thought to lie within Sh2-129 about 2,300 light years away, which makes the Squid about 50 light years in length. The colours of emission nebulae are due to the gas they are made of being excited by energy from a star. Red comes mainly from hydrogen atoms. The teal colour of the Squid comes from atoms of oxygen. Both are excited by the bright triple star system near the centre of the Squid. The Oiii is seriously faint and not only took many hours to capture from a bottle 5 sky, but also really difficult to process.
