		| Abstract: | 
		The hydrogen deficient central star of the PN M2−29 exhibited an RCrB-like brightness minimum, but much longer-lasting. The nebula consists of a nearly spherical ring and a monopolar jet-like structure. The images and spectra collected by us show a surprisingly static nebula surrounding a WELS star in a binary system. |
