One very, very small part (quite large) of the Orion Nebula.

Now I checked the PhotoZ, even if we deduct the Errz that would still make it millions of light years from us and not 1344 light years. So for me it's a HH (which is also how it's noted in SIMBAD). Anyone else?

incorrect photoZ in pretty example in Orion's sword
What a pretty sight! And it is visible to the unaided eye in the night sky, the red blob in Orion's sword.
A good example of how photoZ is sometimes wrong. It has photoZ of 0.237 If it is in our galaxy, it's redshift should be zero. z=0.00 The Orion nebula is about 1,500 light-years away.
You can judge the distance of galaxies by their colours.
