Large and round spiral galaxy that is seen face-on. 
At 203X M99 appears very smooth, rather like an elliptical. There is only
a slight brightning toward the middle and I saw no trace of spiral structure.
The outer regions of this galaxy smoothly fade into the background sky.
There is a star superimposed on its northern edge.
There is a sketch on this object on my homepage: URL mentioned below.
