Gyulbudaghian's Variable Nebula

In this picture of Gyulbudaghian's nebula, North is down. It was ~ 8 mins worth of exposure on the 20" scope nearly overhead (5x1' + 6x30" + 17"). The nebula, which was discovered to be variable in 1977, has been very, very faint recently. The white lines point to the star PV Cephei, which is also faint. If you compare it to a previous image you will wonder what has happened to it... Strange star! (image courtesy STSci)
