Gyulbudaghian's Nebula GM 1-29 and LBN 468

Gyulbudaghian's nebula GM 1-29 was discovered by astronomer Armen Gyuldubaghian while systematically inspecting the POSS plates searching for Herbig-Haro objects as part of his doctoral thesis. Many of his finds were subsequently examined in more detail at the largest telescope in the world at the time, the Soviet 6m telescope in the Caucasus, and were included in the GM catalog. It quickly became clear that Gyulbudaghian's nebula is a bipolar reflection nebula with high variability and is illuminated by the variable star PV Cep.

Within months the shape changes and since its discovery many variations between a full fan and “almost completely invisible” occurred. These fast variations had been the motivation for my visit – when weather permits I would like to document the variability (which is probably subject to similar mechanisms as Hubble's variable nebula) over the next years.

Embedded in the faint clouds of LBN 468 the entire region offers plenty of photogenic dust, which I also tried to capture, but was only partially possible due to the relatively small FOV.

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.
