The Iris and the Clouds of Cepheus

The Iris nebula on the left is a bright reflection nebula in the constellation Cepheus and lies some 1300 light years away. Throughout the frame are dense dusty regions that block out the light of background stars. Some starlight still passes, but is more red in color. The preferential scattering of blue light allows the red light to pass through, in the same way sunsets are red, and our sky is blue. This also gives the Iris nebula its distinctive blue color near the bright star SAO 19158.

Throughout the frame are additional dusty regions that stand out from the background including LDN1158 to the right.

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.
