description Gyulbudaghian's Nebula Overview
Gyulbudaghian's Nebula, also designated GM 1-29, is a faint variable nebula in the constellation Cepheus. It is associated with the young variable star PV Cephei, whose changing brightness alters the amount of light reflected by surrounding dust. The nebula was identified in 1977 and has been observed changing from a narrow streak to a broader fan-shaped form, sometimes fading almost completely. Its variability makes it a target for detailed astronomical imaging.
