OBJECT DESCRIPTION AND IMAGE SESSION
RCW 21 is an amorphous planetary nebula with two lobes that have pointed symmetric extensions. The object is also known as ESO 313-0; PN257.5+00.6 and VBRC1. It is located in Vela close to the borders of Pyxis and Puppis. There are no much images on this planetary nebula. Possibly overlooked because of the many beautiful gems on the area.
RCW21 is part of 180 objects of the RCW catalogue that was published in 1960 by Alex Rodgers, Colin Campbell and John Whiteoak under the direction of Bart Bok.
