SH2-117

SkyEye Observatory 2019

Sh 2-117 is composed of the North American and Pelican nebulae, NGC 7000/IC 5070/IC 5067, which are visible through gaps in the Rift system of dusty giant molecular clouds that separates the Gould Belt from the Cygnus X complex.

Sh 2-117 appears to be ionised by the O5V star 2MASS J20555125+4352246. This star is heavily obscured by the dust in the Lynds dark nebula LDN 935, a Rift cloud which lies at a distance of about 520 parsecs in front of Sh 2-117, and appears to divide the North American and Pelican nebulae.

The radio source W80 appears in this direction. A 2009 paper concludes that W80 is generated only partly by Sh 2-117 and includes emission from 4 distinct sources located at different distances along the line of sight.

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.
