The planetary nebula Jones-Emberson1 (JnEr1, PK164+31.1) is 1600ly way, around 4ly diameter. Its visible size is around 6'x7' spreading 14m which makes the surface brightness very low. The blue dwarf in the center that is driving the whole show is just 16.8m. And this is a spectacular show! Earth size dwarf is emitting enough UV power to blow and lit ~4ly big bubble!

This target is in my list for long time and decided to give a try as first light of new filters. It was not the best part of its season and lost a clear skies weekend struggling with hardware problem in filter-wheel... However managed to get some light and assure why Astrodon filters are so highly rated

Definitely in the next season will take 3-4 times more total exposure and hope to fix the star elongation problem by then...

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.
