There are two large telescopes that they rent out. The 60-inch is $1,050 per half night and $1,700 per full night for a group of up to 25 people. The 100-inch is $2700 per half night and $5000 per full night for up to 20 people. Both telescopes offer amazing views but the 100-inch is the more interesting and historically significant machine.
I did not know that so I can't answer that question
