Constellation Virgo has 9 and 15 stars?

Question

I have been looking at the Virgo constellation and have found that sometimes the pictures I find show 9 connected stars where other pictures show 15 stars... why?

Answer 1

It depends on the limiting magnitude of the illustration.  Some pictures show fainter stars, so there will be more than you can see in other illustrations.

Here's a photo.  It shows a few more than 15 stars.
