I described it pretty good, but okay, I'll get one up as soon as I can.
Edit: Okay, here is what it looks like. Even though the pulse star (it's FiahOwls save) is visible as a box from light years away, I chose a more normal star for the example. This one just happens to be white, but if the star is orange, the box will be orange.

Further in, the box begins to fade and ths star appears as normal.

Hrm, I wanted to get the UI to appear, but for reference anyway, the first one is between 2-1 AU out and the second one is approx 25-20 M km out.
