Image Description and Details: Sh2-224 is a supernova remnant visible in the northern constellation of Auriga. The object has an unusual shape, to me it looks like a paddy field or gendarme hat, in fact it has a shell structure and is interacting with a cavity in the interstellar medium at a higher temperature than the surrounding environment, located in the southwestern part and arched shape. The distance of the structure is estimated at 14,700 light years from the solar system, in a peripheral region of the Perseus Arm. Through the X-ray study, the age of the structure was determined to be between 13,000 and 24,000 years. Taken on several nights between the old and the new year for around 33 hours, I am satisfied with the performance of the 2 interacting gases, the reddish hydrogen and the green oxygen, these single narrow band shots with Ha and O3 filters I combined it with a broadband RGB session with the 3 different filters separately to give more color to the supernova nucleus and to the stars.
