Variable star AE Aurigae is a runaway star passing through the Flaming Star Nebula, the intrincate cloud shown left of center. In this orientation (north is down), the whole complex, comprising several nebulas, may resemble a warrior wearing a bluish helmet, IC410, and raising its right arm, IC405. In his/her chest, the bright spot is IC417. The scene also features the open clusters M36 and M38.

This image was shot under the light polluted skies of Seville city (Andalusia, Spain). In order to overcome the bright sky of a city and gain some contrast, we find ourselves forced to use narrowband filters. Processing is also fundamental to eliminate light pollution gradients and enhance the nebulosity. But nowadays, with the spread of white LEDs and their bright blue emission, even some of these filters won't help anymore. One of the exposures captured also a train of satellites beloging to a future megaconstellation.

We have to recover and protect our night sky.

Orientation: North is down.

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.
