That'll give you the best image with full zoomin-iness.

 

Meanwhile

will give you more blurb (and info, not always necessarily the same thing) as well as natty little videos.

 

I used one of these to localise the region, OO Ser was a good catalogue and skychart/atlas reference point.

 

I must however confess that the purported aligned jets out jumping out of the images to me personally.

 

There's a few Herbig-Haro Objects around there plus some (mainly infrared detected) YSOs, and a coupla reflection nebulae (vdB 123 is the most recognisable identifier I'd noticed) but it seems to be mostly infrared star forming regions so dunno how the astro imagers would fair here.  There's a few objects from the MHO catalogue (ie infrared) and some in the MRN catalogue.

 

Here's some SDSS and PANSTARRS type views for illustration

Nice and complete. Well done post. Love the links.

 

So happy JWST just works. The JWST people should take a bow.

It's been well known for years.

It's been well known for years.

Verbatim as the "Serpens Nebula", a specific object?  Or just nebulosity in general?  Usually these newer or made up common names give me a wikipedia hit when I websearch.  I found

 

Of course there's lots of nebulosity in Serpens and on checker skyviews on wider fields I wouldn't be surprised if some dark bits had

 

If there's a more common name elucidation would be nice.

 

Having said that, it did crop up in SIMBAD as "Ser Nebula" as a reflection nebula with references to the name going back four of the decades or so, but the natal nature only appears in far more recent catalogues I have, an infrared star forming regions one and an infrared clusters one.  Serpens Molecular Cloud I'd heard of, but they can readily not show optical stuff or only patchy bits of it spread about the full extent (even OMC is a bit like that, well, just a little).
