This appears to be a reflection nebula. [Not sure I agree with this- JY]

Faint nebulosity surrounds the B5 star HD 197911, the A0 star HD 197809 and the G5 star SAO 18999. HD 197911 is a runaway star blasted from the heart of the Cep OB2 association by a supernova explosion 2-3 million years ago.

The B5 star HIP 102274 (HD 197911) was located at the center of the Cep OB2 association between two and three Myr ago, when the association was 3-4 Myr old. This kinematic age coincides with the time of the supernova explosion proposed by Kun et al. (1987) to explain the characteristics of the Cepheus bubble, a ring-like structure of infrared emission.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
