NGC 3199 is one of my favourite objects. A UHC filter improves the view.
Here is an image of it:

Dunlop's declination was out by 1 degree but his description and diagram were accurate. "D332. A very faint ray of nebula, about 2' broad, and 6' or 7' long, joining two small stars at the south following extremity, which are very slightly involved, but their lustre is not diminished from that of similar small stars in the field. The north extremity also joins a group of small stars, but they are not involved."
