Description:
 
Another record of this galaxy. The galaxy has a bright central region with a 
not very stellar nucleus. It covers just less than half a field width of the 
9 mm eyepiece and shows some elongation in the 10 o'clock direction, which 
broaden towards the inner part. There is not a lot of definite structure but
 with the 15 mm eyepiece there is an impression of spiral arms coming from 
the nucleus.
