LBN 468 is a dark nebula located in the constellation Cepheus. From my observations, there are way more images of its next door neighbor, the Iris Nebula, and thus I decided to image this guy. There is so much dust in this region that even doing background extraction took very careful placement of points.

A curious object, Gyulbudaghian's Nebula can be seen at the left hand tip of the central dust. This nebula, first discovered in 1977, has been changing in intensity constantly since. It lies at the heart of Herbig Haro 215. Jets of dust can be seen streaming away from the star at right angles but the nebulosity looks very different than images captured as recently as 4 years ago, lightning quick in astronomical timescales.

This image is a 2-panel mosaic totaling just over 40 hours of total integration time from my personal setup at the Dark Sky observatory, near Fort Davis, TX (Bortle 1). Acquisition was taken over 14 nights:

- 7/9, 7/10, 7/16, 7/17, 7/19-7/24, 7/28-7/31/22

- All acquisition in NINA, all processing in PixInsight. Please see Flickr Link for full processing details.

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.
