How far away from our solar system would our Sun still be visable enough to be in an alien constellation?

Assuming their atmosphere was the same as ours and their eyes worked the same.

Only 30-40 light years. Our sun has an absolute magnitude of ~4.9, which by definition means it would have a magnitude of 4.9 when seen from 10 parsecs away (~33 light years).

Our eyes on the clearest nights with no light pollution can only see things brighter than about 5th magnitude, so the sun would already be almost gone at 40 light years. Note that this means that the Sun would only be visible with the naked eye to the nearest ~2000 stars or so!!

This is why almost all the stars you can see in the night sky are much bigger and brighter than the Sun. Even though 70+% of the stars in the universe are M-dwarfs (masses < 60% of the Sun), none of them are visible to the naked eye because they're just so dim. All the stars we can see with our eyes are the much rarer stars that are more massive and luminous than the Sun.
