Description

This was meant to be a longer duration project but between weather and work I ran out of time to collect more data. The small amount I was able to acquire just starts to show some of the faint arm structure around the nucleus of NGC4151. NGC4151 is a Seyfert galaxy and is a frequent target for black hole studies.
