Description A rather obscure field in Centaurus. NGC 5121 is a reasonably bright galaxy (11.5 magnitude) 1.9' x 1.4' in size. The planetary nebula Longmore 8 is 132x108" in size. Of interest is an arc of blue nebulosity to the left of the planetary which may be an OIII bow shock.  There is also integrated flux nebula in this field.

The outer structures around this planetary nebula were discovered by the Galactic Planetary Nebula Halo Survey (GPNHS) team using this image in May 2016
