Welcome to the Peoria Astronomical Society!

The Peoria Astronomical Society is a non-profit organization of amateur astronomers from Peoria, Illinois and the surrounding community.


We meet on the first Wednesday of each month, at 7:30 pm at the Planetarium in downtown Peoria, IL. (Parking info here).
The members' meeting is a great place to meet other members, swap stories, and learn more about astronomy. The meetings are always free and open to the public.

**Event Cancelled** due to severe winter weather, cold and snow accumulation.
January’s Program features two of Central Illinois’ Best Amateur Telescope Makers!
Rich Tennis scope Who builds a telescope when you can buy one so cheap? Well two of our members have done just that; one having just completed his second scope.

Don’t miss our January 7 program where it will be a "Show and Tell" featuring Rich Tennis and Greg Neaveill. Rich completed his 17.5" Dobsonian back in 2005. Greg completed his 10" Dobsonian back in 2009 and just completed his 8” DOB-in-a-Briefcase.

Get a look behind the scenes at what went into their making with a PowerPoint presentation by Rich and Greg. All three telescopes will be at our meeting so you can touch (except the mirrors) and ask all the questions you want. You’ll have to travel quite a ways before you’ll see three finer home-made telescopes . . . perhaps you will be inspired to build your own.

When: Wednesday, January 7th 2015 @ 7:30 PM CST
Where: Peoria Riverfront Museum Planetarium, Downtown Peoria, IL
Format: Live in-house presentation

During the summer months (June, July, and August), we do not hold regular meetings. Instead we plan a star party event each month!
In September, we have our Annual Banquet, which takes the place of our September monthly meeting.

Board Meetings: Our board meetings are held on the third Wednesday of each month at the Hardee's in the Northpoint Shopping Plaza at 7:30 pm, and is open to all PAS members.
