Visible to the naked eye under a dark sky (apparent magnitude 5.86). Visible from the whole Northern Hemisphere and south to latitude 87° S. It stands highest at midnight in May, the best time to observe it.
Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1978. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 856 thousand years.
The Sun seen from there
From a planet around ψ Ser, the Sun would look like a star of magnitude 5.68, in the direction where our sky has the constellation Eridanus. It would be visible to the naked eye.
