IC 4634

This object is a faint tiny planetary nebula located 13,000 light years away in the constellation of Ophiuchus at a declination of -22 degrees. It spans only 15 arc-seconds in our apparent view, a bit smaller than our current view of Mars. This corresponds to a diameter of 1 light years.

The wonderful Hubble image in the mouseover shows the PN in much better detail, including the progenitor star which is not visible in my image. I don’t understand why the OIII doesn’t show up very much in the Hubble image.

This PN looks very similar to Minkowski 3-1. The most striking feature are two 2 bipolar point symmetric HII ejections, visible in both the central nebula and of course the 2 curling end ansae. My PN Ansae Collection is here.

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.
