The Des Moines Astronomical Society, Inc. (DMAS) is here to promote interest in astronomy, and to share opportunities for viewing the night sky. Our Ashton Observatory is home to two 16 inch diameter telescopes. From there you will be able to see the Milky Way and study the deep space objects that are so fascinating, guided by the friendly, enthusiastic and experienced members of DMAS.
