NGC 3699 is a small but moderately bright planetary nebula situated in the narrow strip of Centaurus that seperates Crux Australis and Carina. It is almost half way between the Southern Cross and the eta carina nebula.
In an 8" telescope using high magnification, the nebula appears as an irregular patch of light with a dark patch cutting it in half.
