NGC7023 - Irisnebel

It is a reflection nebula in the constellation Cepheus.
The predominant color of the bright reflection nebula is blue, characteristic of dust grains that reflect starlight.
Central filaments of the reflection nebula glow with a faint reddish photoluminescence as some dust grains effectively convert the star's invisible ultraviolet radiation into visible red light.
The bluish “petals” of the iris are just over six light years in extent.
Within the nebula, dusty material surrounds a hot, young 7-magnitude star, reflecting its light.

Es handelt sich um einen Reflexionsnebel im Sternbild Kepheus.
Die vorherrschende Farbe des hellen Reflexionsnebels ist Blau, charakteristisch für Staubkörner, die Sternenlicht reflektieren.
Zentrale Filamente des Reflexionsnebels leuchten mit einer schwachen rötlichen Photolumineszenz, da einige Staubkörner die unsichtbare ultraviolette Strahlung des Sterns effektiv in sichtbares rotes Licht umwandeln.
Die bläulichen „Blütenblätter“ der Iris haben eine Ausdehnung von etwas über sechs Lichtjahren.
Innerhalb des Nebels umgibt staubiges Material einen heißen, jungen Stern von 7-Größe, dessen Licht dadurch reflektiert wird.

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.
