I photographed this over 2 nights with my 10" f4 astrograph using an unmodified Nikon Z7 and an Antlia dual 5nm narrowband filter with 5 hours, 36 minutes of exposure at ISO 1600. Here's some great information about this beautiful object from Wiki:
NGC 7380 is a young
[4]open cluster of stars in the northern
circumpolar constellation of
Cepheus, discovered by
Caroline Herschel in 1787. The surrounding emission nebulosity is known colloquially as the
Wizard Nebula, which spans an angle of 25
′. German-born astronomer
William Herschel included his sister's discovery in his catalog, and labelled it H VIII.77. The nebula is known as S 142 in the 1959
Sharpless catalog (Sh2-142).
[2] It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter. The NGC 7380 complex is located at a distance of approximately 8.5
kilolight-years from the
Sun, in the
Perseus Arm of the
Milky Way.
[2]The cluster spans ~20 light-years (6 pc) with an elongated shape and an extended tail.
[2] Age estimates range from 4
[2] to 11.9
[1] million years. At the center of the cluster lies
DH Cephei, a close, double-lined
spectroscopic binary system consisting of two massive
O-type stars. This pair are the primary ionizing source for the surrounding
H II region, and are driving out the surrounding gas and dust while triggering star formation in the neighboring region.
[4] Of the
variable stars that have been identified in the cluster, 14 have been identified as
pre-main sequence stars while 17 are
main sequence stars that are primarily B-type variables.
