Planetarium

Today i saw Birla planetarium.
What they showed there is the most elementary information about stars.They no longer show the planets in the planetarium,as they used to.
Do they not have a moral obligation to publicise the change in the content? Is it not simple cheating?
Furthermore , I could not locate a site of their own in the internet .whatever information we get from general Hyd tour and hotel establshment sites is all that is availble for us.
