The Boise Astronomical Society is proud to present the

31st Annual Idaho Star PartyTM
September 11 - 12, 2015

at the Bruneau Dunes State Park.

What is a Star Party?

A Star Party is a gathering of amateur astronomers under the stars! Many people who attend star parties bring telescopes, but you certainly do not need one to attend the ISP. The Bruneau Dunes State Park features a public observatory that hosts a number of high quality telescopes that are for everyone's use, including an outstanding 25" Newtonian Reflector. Additionally, most amateur astronomers are happy to share their instruments!

The Idaho Star Party is an event for the entire family, with programs for all ages, including kid programs, door prizes, and guest speaker presentations.

What do I need to do to attend the ISP?

You could simply get yourself to Bruneau State Park sometime between September 11th and 12th, but if you want to participate in the programs and events you must register for the ISP.
