NGC 3195 (also known as Caldwell 109) is a planetary nebula located in the southern constellation of Chamaeleon. It is the most southern of all the bright sizable planetary nebula in the sky, and remains concealed from all northern observers. Discovered by Sir John Herschel in 1835, this 11.6 apparent magnitude planetary nebula is slightly oval in shape, with dimensions of 40×35 arc seconds, and can be seen visually in telescopic apertures of 10.5 centimetres (4.1 in) at low magnifications.
