This relative big Planetary Nebula,named Abell 34 or PK248+29.1,is a very dim one and can be found in the constellation of Hydra with an apparent size of 4.8 x 4.8 arc-minutes and a visual magnitude of 14.5mag.Visually best observable in OIII-filters,it is nevertheless a challenge even for photographic observers.
Compare the two versions down at this page,showing the very prominent OIII-colors in the upper picture as well as the pure RGB-version down at the bottom.
