More on Boren’s nebula

Yesterday, I told you about a new nebula imaged by Israeli amateur astronomer Harel Boren in a wide-field image of the dark nebula Barnard 171 in Cepheus.

In Boren's words, the object is "a long red (and possibly a little blue) emission nebula that resembles a shock wave as visible in other objects. It is located a little north of Barnard 171 as a slightly curved wave rolling from west to east, and is about 16 arcminutes long and 1 arcminute wide."

Here is an update from Boren: "The object lies just north of Barnard 171, and the exact coordinates of its center , in equinox 2000.0, are: 21h58m53s, 58°46'04". I have also checked in Aladin Sky Atlas, at the exact coordinates above, and could see nothing there. One of my friends here, Ido of Bareket Observatory, had suggested that the object may actually be a new one (i.e. physically nonexistent when earlier images where taken). I don't know if it's that or just a combination of good seeing and a good supernova remnant. I hope it's existent, and I sure hope it's new — as it's a true thrill for me."
