RVB: 3x30x180sec

LDN 43- the cosmic bat nebulae voilà une nébuleuse que je ne pensais pas faire depuis notre hémisphère au vu de sa hauteur! Elle est plutôt basse et située dans ce qui devrait être le 13eme signe du zodiaque: le serpentaire. (Ophiucus)

LDN 43 est un nuage moléculaire située à 1400 année lumière. Ces vastes nuages moléculaires riche en poussière occultent la lumière de presque toutes les étoiles qui brillent derrière.

LDN 43 (Lynds catalog of dark nebulae) vient de son apparence à une chauve souris semblant volée au dessus d’autre nuages de poussières. Il s’étend sur environ 12 années-lumière. Une jeune étoile l’illumine de l’intérieur permettant cet effet saisissant.

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.
