History

The small planetary nebula IC 2149 was discovered in 1906 by the Scottish-American astronomer Williamina Fleming photographically and visually-spectroscopically with an 8 inch telescope. She was an assistant to Edwart Pickering, an astronomy professor at Harward University. [196, 277]

Physical Properties

The physical structure of this bipolar planetary nebula is not yet completely sure. It could be a bright ring of gas that we are looking at from the side, or it could be a jet extending northeast and hitting a shock front. The distance to this PN is estimated to be about 1.1 kpc. [449, 450]
