Through a telescope from Earth
Light's journey
The light you see tonight set out around the year 1368. At the speed of Voyager 1, the fastest craft leaving the Solar System (16.9 km per second), the trip would take 12 million years.
The Sun seen from there
From a planet around ZTF J1828+2308, the Sun would look like a star of magnitude 11.35, in the direction where our sky has the constellation Canis Major. It would be invisible to the naked eye.
