Supernova Remnant SNR G065.3+05.7

‍Description and Details: A supernova remnant in the constellation Cygnus, formed approximately 27,500 years ago, with a pulsar hidden at its center. Often overlooked due to its brighter neighbor, the Veil Nebula, there are very few images online with such short exposure times and taken under polluted skies. For me, this shot represents a great achievement: both for the evanescence of the subject and because I had never accumulated so many hours on a single target!
