NGC 6781

This object is a 1.8 minute diameter planetary nebula located in the constellation of Aquila, 3000 light-years from Earth. In my narrowband image above, the bluish star at the center of the nebula that created the planetary nebula is barely visible. This star is much more apparent in the RGB image, which is not included here. The bubble is about 2 light years in diameter. This is a bi-color nebula image because there was little SII signal to capture.

It is believed that we are looking almost directly down the polar axis of this bipolar, two lobe nebula. The lobes are seeing some breakout of hydrogen gas.

This object is nicknamed the snow globe nebula. I love snow globes, but I have mixed feelings about this nickname.

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.
