First, I found the 'preferences' button in 'my account' page.
Clicked on the seti options. set the 'custom' option.
Then, I noticed I had new options now.
Set the background image to something from Astronomy picture of the day virgo_dss (saved it as a jpg to make it work)
Set the number of stars to 5000
Turned down the oscillation.
Set the graph grow/hold to 0 0
Selected the heads up display instead of pillars.
This is the background pic I used.
