Description

LBN 468: dark nebula in Cepheus with two interesting features at the top (PV Cephei - Gyulbudaghyan Nebula) and the bottom of the frame.

According to the Britisch Astronomical Society: "Gyulbudaghian’s nebula was discovered by Armenian astronomer Armen Gyulbudaghian in 1977 and the variability of the nebula was shown by Martin Cohen four years later. Associated with the variable PV Cephei, it has undergone remarkable changes in the last decade making it the most popular of the variable nebulae for the more advanced amateurs. When discovered, it showed as a thin ribbon. Then it was seen to fan out and brighten, only to fade and brighten erratically during the later months of this decade, reverting to a ribbon again before disappearing during the autumn of 2020. It may well brighten again soon."

Personal note

Another interesting part of Cepheus with not just fascinating dust clouds but also bright objects against a dark star field. Happy with the end result but maybe a bit too red on the clouds and too blue in the fainter parts?. Difficult to get the masters completely flat and getting the color distribution correct without destroying the fine details in the faint dust features.

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.
