Minkowski 4-9

This object is a tiny obscure planetary nebula located 6000 light years away in the constellation of Serpens at a declination of -5 degrees. This PN spans 45 arc-seconds, which looks slightly larger than the planet Jupiter to our apparent view. The actual diameter of this PN is about 1.3 light years.

I couldn’t find anything on this object in the literature. I imaged it because I liked how it sits next to a series of dark nebulae. It has a typical PN look, with a bright red Ha rim that surrounding a bluish OIII central region. The rim is narrower and more sharply defined left and right, and more diffuse top and bottom. The bluish central star is plainly visible.

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.
