What is this?

Came across this asterism (cluster?) on Sept. 14 while tracking down NGC 7226. Re-observed it tonight and made a sketch. Was able to resolve thirteen stars involved with the “Y”-shaped asterism, which is about 2'x2' in size. Not plotted in Uranometria 2000.0 (first edition or latest all-sky edition). Not listed in Archinal/Hynes “Star Clusters”. Epoch 2000 position: RA 22 13 44, Dec +55 44. Attached DSS image is 10'x10' square; about 35 stars seem to be involved. Haze on left side of image is from Sharpless 2-132. Group is well separated from sky background and sticks out like a sore thumb at low and medium magnification. Anyone know if this is catalogued somewhere... a cluster?... an asterism? Nothing at all????

According to Simbad, this is a cluster of stars called Teutsch 126. See:

If anyone ever comes across such a group or stars (or anything else) that does not carry a designation, report it to the Deep Sky Hunters Yahoo Group. This cluster Teutsch 126 also carries the designation DSH J2213.7+5543. A new list of potentially new DSH objects is in the making.
Find something unidentified and it just may get your name attached to it. Places to check are SIMBAD, NED and catalogs in applications such as AstroPlanner, TheSky X, etc.

Thanks guys!!!!

As Mark effectively posted his observation of Teutsch 126, I will add mine ;-)
Logged two observations using my 12" SCT. The cluster is part of the 12" Cep OC-1 guide in CSOG.

A small group of stars. In the center of the cluster are two mag. 10 stars aligned east to west with a mag. 12 star directly ESE of the eastern star. Three times that distance towards the south is another mag. 12 star. To the south is the double star Stein 2652: a mag. 10 star with a mag. 11 component at a PA of approximately 275. To the south of the two mag. 10 stars is a glow of unresolved stars, slightly resolving with use of AV (mag. 14 and fainter).
Rated it 2/10.

Not very detached, an arrow shape pointing WNW, a "Y" with the open side towards the ESE with double stars(?) in both the SSW and the NE side of the "Y": The eastern pair consists of a mag. 9.5 star with a mag. 11 star to its west. This is the double star Stein 2653, AB split.
The NE pair is just a little wider, a mag. 10.5 star with a mag. 12 star to its east. This is the double star Stein 2652, AB split.
A remarkable shape. In the "Y-shape are several mag. 14 and fainter stars. To the SE of the "Y" are a mag. 11 (NNE) and a mag. 11.5 (SSW) star aligned NNE to SSW.
Rated it 3/10.
