The Highland Road Park Observatory (HRPO) is located in the Highland Road Park and offers free Friday night sky viewings (using a 20-inch reflecting telescope). Prior to the viewing they hold a lecture from professors and/or graduate students from LSU's physics and astronomy departments.
I've been twice now and always enjoy it.
Here are the stairs leading up to the telescope (sky viewing) area
Oh and they have the best coffee (for a minimum donation)!
If you're in the area, check them out next Friday. You can view the lecture series via their website here.
