Sh2-280 è una nebulosa a emissione visibile nella costellazione dell'Unicorno.Si osserva nella parte centro-settentrionale della costellazione, circa 2° a sud della Nebulosa Rosetta; può essere fotografata senza eccessive difficoltà attraverso un telescopio amatoriale di media potenza munito di appositi filtri, anche se sono necessarie lunghe pose. Essendo a soli 2° di declinazione nord, può essere osservata da tutte le aree popolate della Terra con facilità; il periodo più propizio per la sua osservazione nel cielo serale va da dicembre ad aprile.Si tratta di una regione H II di grandi dimensioni, posta sul Braccio di Perseo nella stessa regione galattica della Nebulosa Rosetta e dell'associazione OB Monoceros OB2, a circa 1700 parsec di distanza, e dell'ammasso aperto; la ionizzazione dei gas della nube sarebbe ad opera della stella blu di sequenza principale HD 46573, di classe spettrale O7 e magnitudine 7,96, posta al centro della regione nebulosa. A questa si aggiunge la gigante blu HD 46847, di classe B0III e di magnitudine 8,97 e situata sul bordo nordorientale della nube. Le regioni circostanti ospitano anche altre nubi di gas ionizzato, come Sh2-282.

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.
