All About

The Neville Public Museum Astronomical Society (NPMAS) is a fellowship of amateur astronomers. We join together to share learnings, experiences, and the passion we have for astronomy. We nurture and promote this interest through our activities. The foundation of our endeavors is the enjoyment we share.

Public Observing Nights

Join the members of the NPMAS throughout the year as they set up their telescopes and binoculars for public viewings of night sky objects including the moon, planets, stars and galaxies. Observing will take place at the Danz Avenue entrance to the Wildlife Sanctuary. All Public Observing Nights are free.

Community Outreach

NPMAS provides, free of charge, astronomy-related programs, presentations and/or star parties to scout groups, schools and other interested groups or organizations.

Star Parties

Star parties are an important part of our club activities. Members bring their telescopes to a dark sky site. Beginning members get a chance to learn the night sky on an individual basis with the more experienced observers. Experienced observers get the chance to further their own development by observing more difficult objects. Members have access to various star parties in and around Wisconsin to improve their skill and knowledge of the night sky.

Other Activities

Include field trips, club picnic and holiday dinner party. Weekend trips include Camp U-nah-li-ya Winter Weekend, Wisconsin Observer's Weekend, Parmentier Observing Weekends, Kroes Observing Weekends, Amberg Star Party, Northwoods Starfest, Northern Nights Star Fest, as well as regional and national conventions.


NPMAS is a member of the Night Sky Network, an association with NASA, JPL and the ASP to bring astronomy to the public in a fun and engaging way. We are also an Astronomical League Member Society.
