Fred Lossing Observatory FLO

The Fred P. Lossing Observatory (FLO)

FLO is operated by RASC Ottawa chapter for the benefit of its members. Members may bring their own observing gear or, if certified, use one of the permanent club telescopes.

The observatory was established in 1971 and celebrated its 50th anniversary in 2021.  It has been located at the current site since 1977. Recent improvements have increased the number of permanent telescopes and observing areas.

FLO is located in relatively dark skies just outside of Almonte, about 45 km west of the Highway 417/416 interchange. We lease a portion land at the Mill of Kintail Conservation Area, leased from the Mississippi Valley Conservation Authority. The observatory is accessed from 365 Bennies Corners Road via a private gated lane.

At RASC Ottawa we hope to inspire your interest and foster your knowledge of astronomy. Whether you’re a seasoned observer or just beginning to explore the wonders of the cosmos, we have expertise and resources to offer. Our vibrant community of members shares a passion for all things astronomical, and we are here to support and guide you on your astronomical journey.
