Too faint for the naked eye (magnitude 7.88); binoculars will find it. Visible from the whole Northern Hemisphere and south to latitude 81° S. It stands highest at midnight in August, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1973. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 936 thousand years.
The Sun seen from there
From a planet around Gl 824, the Sun would look like a star of magnitude 5.87, in the direction where our sky has the constellation Hydra. It would be visible to the naked eye.
