Cederblad 214 (located slightly above the middle of this field) is a large emission nebula in the constellation Cepheus.  It is part of a complex that also includes a fainter, arch-like nebulous expanse known as NGC7822 (located near the bottom of this field).  There is a small, magnitude 18.3 planetary nebula (PLN 119+6.1) in the lower right hand portion of this field, best seen on the larger view- can you find it?  As can be appreciated by the "donut hole" in the lower part of this complex, this star-forming region is being cleared out by young, newly formed stars emitting strong UV radiation, reminiscent of similar nebulae such as IC1396 and the Rosette.  More information about this interesting region may be found on Rob Gendler's webpage, and on the APOD website.   Please check out the larger image and the cropped views in the links above.
