Description:
At 131x NGC 3198 extends approx 6x2’. The core is very small and faint but
appears non-stellar. The bright halo extends NE-SW, surrounded by a few
11-14mag stars. On it’s W edge the halo fades away abruptly and with averted
vision it looked like a dark lane running along the W side of NGC3198 was
visible.
The high surface brightness makes this galaxy an easy and nice target.
