 Best Viewed Objects/Stars

Alpha Fornacis

 The brightest star in the constellation, appearing to the naked eye as a single star of magnitude 3.8. A small telescope shows that it has a 7th-magnitude companion. The two stars form a true binary, orbiting each other every 300 years or so. They lie 46 light-years away from Earth.

Fornax Cluster

 A cluster of galaxies about 75 million light-years away, the brightest of which, notably NGC 1316 and NGC 1365, can be seen with a small telescope. NGC 1316 is a peculiar spiral, also known as radio source Fornax A. NGC 1365 is a barred spiral.
