The Spider and Fly Nebulae : IC 417 and NGC 1931

The Spider and Fly nebulae are situated in Auriga, at around 10 000 and 7000 ly away. They are emission nebulae.

This is a Hubble palette, the Oxygen is very weak and mostly present in the Spider nebula. The nebula is pretty faint, but due to the 24h of exposure I managed to emphasize the dark clouds in the background.

Shot on multiple nights : 23/09; 01/10; 08/10; 11/10; 12/10; 18/10. Mostly with the 1600MM, and a few hours with the 2600MM.

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.
