Here we have the Pleiades aka Messier 45, bathing amongst the very faint golden galactic cirrus which spans across the constellation of Taurus. The dust that you see here is actually not emitting light but rather reflecting. It is partially illuminated by the bright 7 stars within the Pleiades and additionally illuminated by our milky way galaxy.

I am unclear of the distinction between IFN and galactic cirrus, Galactic cirrus seems to be closer to the core of the milky way. IFN and Galactic cirrus both actually appear in IRAS and Planck thermal dust surveys. Regarding molecular structure, I have read that IFN is comprised of Polycyclic Aromatic Hydrocarbons which are essentially leftover burned up carbon remains. The IFN reflects light predominantly at 540nm up through 950nm according to Mandel Wilson.

Capturing Galactic cirrus and the bluish gray dust surrounding the pleiades requires very dark skies and deep integrations of data which must be carfeully processed. I am not 1005 happy with this image yet and there may be a few more renditions, but I hope you enjoy what I have presented.

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.
