Gyulbudaghian 98-171 (Gary Imm)

Celestial hemisphere: Northern · Constellation: Cygnus (Cyg)

Gyulbudaghian 98-171

This object is a tiny cometary nebula located 2000 light years away in the constellation of Cygnus at a declination of +50 degrees. A cometary nebula is a fan-shaped reflection nebula whose source star lies at the vertex of the fan. The most well known example of a cometary nebula is Hubble's Variable Nebula.

The nebula surrounds the young stellar object V1982 Cyg and is about 1 light year wide. V1982 Cyg is the bright white star at the upper right of the nebula. I believe that the orange star (HBC 727) at the lower left edge of the nebula is only a line of sight coincidence and is not connected to the nebula.

Several bright white arcs focused back on V1982 Cyg are seen in the nebula, which I find to be interesting. The dark nebula on the right side of the image is LDN 988.

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.
