Slightly above and to the right of the center of this image is an object called Gyulbudaghian's Nebula, named after Armenian astronomer Armen Gyuldubaghian who discovered it in 1977. This bright yellowish, fan-shaped structure is a so-called Herbig-Haro object, which means it is a newborn star (in this case PV Cephei) shooting out two jets of gas in opposite directions from it's north and south poles. In this image we can only see one of the jets as the other one is mostly obscured by dark molecular dust. This object catalogued HH215 or GN 20.45.4, is actually changing in intensity over only a few years, which is quite fast in astronomical timescales. Luckily, the HH215 was really bright at the time of these exposures. IN images shot as close as 2012 the fan is much less visible. The dark and dusty nebulae stretching downwards from the center of the image is called LBN 468 and contains amongst others LDN1158, LDN1157, LDN1148, LDN1155 and Rno 124 Cepheus.
