214 (Ced214, SH2-171) is a large
emission nebula in the constellation Cepheus. Within
Ced214 there are many
regions of "elephant trunk" structures created as a result of gas being
blown away by UV radiation from one of the brightest UV sources in the
nebula, the star BD+66 1673 (RA 00 01 47; Dec +67 30 25, J2000).
This star is contained
cluster of about 40 hot, short-lived OB stars known
as the Berkeley 59 complex (Be59, labeled in the rollover), located
above center in this field. As
can be appreciated by the "donut hole" in the central part
of this complex, gas in this star-forming region is being cleared out
the young, newly formed stars of the Berkeley 59 complex, which emit
strong UV radiation, reminiscent of
similar nebulae such as IC1396 and
A more detailed view of this region is shown in my
prior images taken through SII, Ha, and OIII filters.

Scope/Camera: The widefield "palette" for this image was
obtained on September 2, 2022, using the a self IR-modified Canon T7i
in conjunction with the Samyang/Rokinon
135mm lens/Canon T71 (5.8"/pixel) on a Star Adventurer mount (9 degree x 6 degree FOV). Additional
Ha and RGB data of this
region were also obtained on September 1 and 2, 2022, using my FSQ106/U16M (3.5"/pixel).
The cumulative imaging time to produce the above image was
approximately 10 hours.
