IC 417 / Sh2-234 (with NGC 1931)

These objects are located in the constellation of Auriga at a declination of +34 degrees. IC 417 (on the right) is about 7000 light years away, while NGC 1931 (on the left) is about 10,000 light years away. It is interesting that the IC 417 designation is for the HII emission nebula while the NGC 1931 designation is for the open star cluster.

Each object consists of an open star cluster energizing the gas nebula around it, with IC417 containing the star cluster Stock 8 and NGC 1931 containing its namesake cluster. The space between these two objects appears relatively free of gas and dust.

The thin dust pillar of IC 417 is about 1.5 light years long.

These objects are nicknamed the Spider Nebula (IC 417) and the Fly Nebula (NGC 1931). Both objects just missed making my Worst DSO Nicknames poster.

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.
