Bright stars or Nebulas ?

Bright stars often create a cross-hair shape because of the light overloading the telescope detectors, but like in this example, they don't expand beyond the circle in WISE. This is a common mistake when you start classifying in Disk Detective.
In the tutorial the example shows an object that expand all over the screen, that it's classified as a nebula.
A star is a good sign, because around them is where we can find disks.
I'll ask TED 91, to make a post with examples and clear doubts.
