Ced 214 is a bright nebula described in the 'Deep Sky Field Guide' to U2000 as "...brightest in the NE sector. The N part is broken up by absorption patches."
Giving Sharpless his due, CED 214 is the brighter part in the bottom center of the image, the remainder of the nebulae is designated SH2-171.
There is a tendency to label this nebula as
NGC 7822. If you go with U2000, the Cederblad catalog, the original NGC
catalog, Simbad, etc., NGC 7822 is 1.5 degrees North. If you
go with the revised NGC catalog NGC 7822 is a 20'x4' strip (orientation not
specified) of sky centered on the open cluster Berk 59 (at lower center left)
and does not encompass CED 214. I like the original
NGC 7822 as opposed to an open cluster, I don't
think Herschel made a mistake.
The following 15'x15' image is from the DSS
for the coordinates of NGC 7822 as modified by the Project.
The Project did keep the original size (20' x 4') which more fits the
Herschel's object but seems hard to reconcile to the above object. The Project
also references Ced 214a and 214b which do not appear in the Cederblad
catalog.
Of real interest is the fact the visual observing report used by the Project reported visually identifying faint nebula at the original NGC 7822 location but was unable to identify nebulosity in either Ced 214 or the project location for NGC 7822. Herschel saw it, Draper didn't but cautioned his pointing might not have been accurate and Roberts used 90 minutes photo plates to detect Ced 214 and didn't even address the nebula at the Herschel location.
Go to the following and click on NGC 7822 for the Project's discussion on changing the location of NGC 7822. http://ngcicproject.org/dss/dss_n7800.asp
Note the Project indicated the new location was also cataloged as Ced 215 generating another catalog discrepancy for some future project to correct. The following are the notes from the original Cederblad catalog -
214 The nebula surrounding the two stars +66 1676 = HD 224992, and 214 +66 1679 = HD 225216 = Boss 39. R. Erroneously identified as NGC 7822 214 by Roberts in (624). (630 Pl 20). 215 NGC 7822 = GC 5051 = h 2302. R. The coordinates and the description given 215 by John Herschel must refer to the nebulous cluster containing the HD 215 stars: +68 1423 = HD 225123, and +67 1588 = HD 224825. 215 Compare (630) Pl 20.
