NGC 136 and OU2

This lovely pair of objects is located in the constellation of Cassiopeia at a declination of +61 degrees, about 1 degree east of Sh2-173 (Phantom of the Opera Nebula).

NGC 136 is a magnitude 11 open cluster of about 20 stars located 17,000 light years away. The cluster is only about 1 arc-minute wide, which corresponds to a diameter of 5 light years.

OU2, also known as PN G120.4-01.3, is a small faint planetary nebula discovered just 12 years ago. No narrow field images of this object exist on Astrobin and little information exists on it. It is about 1.2 arc-minutes in diameter. If it is the typical PN diameter of 2 light years, it lies about 5000 light years away. Its structure is unusual – a round OIII region with a large rectangular void in the center. The progenitor star is suspected to be the very faint small star in the exact center of the nebula.

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.
