The Iris Nebula (Caldwell 4) is a reflection nebula in Cepheus 1300 light-years from Earth. Within, we see a hot newborn star, HD2000775, of 10 solar masses emerging from a massive dust cloud. It's solar winds have cleared a surrounding bi-lobed zone measuring 5 x 2.5 light years. The surrounding dust scatters the star's visible light, just as our atmosphere scatters sunlight in the sky, rendering the nebula sky blue.
The blue nebula is surrounded by dark obscuring clouds of dust. While the Iris nebula is often referred to as NGC 7023, this is not strictly correct. NGC 7023 refers to the associated open star cluster to the west. The correct designation for the nebula itself is LBN 487.
Found it difficult to bring out the dust cloud and process the nebula, also found that the blue nebula expensed throughout the back ground. I think I needed a few more hours of exposure, Had to use Photoshop this time to process this complex nebula.

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.
