Explanation: Like an illustration in a galactic Just So Story, the Elephant's Trunk Nebula winds through the emission region and young star cluster complex IC 1396, in the high and far off constellation of Cepheus. Also known as vdB 142, this cosmic elephant's trunk is over 20 light-years long. The detailed telescopic view features the bright swept-back ridges and pockets of cool interstellar dust and gas that abound in the region. But the dark, tendril-shaped clouds contain the raw material for star formation and hide protostars within. Nearly 3,000 light-years distant, the relatively faint IC 1396 complex covers a large region on the sky, spanning over 5 degrees. This rendition spans a 1 degree wide field of view though, about the angular size of 2 full moons.

Far off constellation of Cepheus? Don’t all the constellations extend equally far off?

NICE!
On average, yes!
But, the furthest star you can usually see without a telescope is Deneb in Cygnus at ~1500 l.y. Everything else you can see is closer, so, nothing is really that distant compared to the rest of the Galaxy.
The Magellanic Clouds and the Andromeda Galaxy can be seen with the naked eye (under good viewing conditions) and they are much further away than Deneb. Of course you can’t pick out individual stars in those galaxies with the naked eye.
