Sh2-150, Sh2-145, Vdb154 Reflection Nebula

Sh2-150 is the emission nebula to left of center, and VdB-154 is the blue reflection nebula on the right. “VdB” refers to the van den Bergh catalogue of reflection nebulae. Sh2-150 lies about 2900 light years away in the constellation Cepheus.

Emission nebulae glow red due to energy released from excited hydrogen atoms. The energy is absorbed as infrared light from nearby stars. Reflection nebula don’t emit light. As their name suggests, they reflect the light of stars near them, and tend to be blue or yellow. In this case the red of Sh2-150 and the blue of VdB-154 impart a purplish hue to the right-central region of the image. Scattered throughout the image are several areas that are relatively free of stars. These soot and dust in these dark nebulae block out the light of stars behind them.

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.
