IC 418

Yes, there is a DSO object in the star field! This object is a tiny planetary nebula located 5000 light years away in the constellation of Lepus at a declination of -13 degrees. This PN spans 20 arc-seconds in our apparent view, about the same as Saturn, which corresponds to a diameter of 0.5 light year.

This object is nicknamed the Spirograph Nebula because of the strange inner texture pattern which appears in the Hubble image. My equipment is not sufficient to show such a pattern.

This nebula is tiny but so bright that it allowed me to take an RGB image, so unlike the Hubble image, the colors here should be representative of the actual nebula. The bright 10th magnitude central star is clearly visible. I found it interesting that the color of the nebula is a slightly different shade of red on the top vs on the bottom, which could be an artifact but I have seen that also on another RGB image of this object.

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.
