SH2-192

Sh2-192 è una nebulosa a emissione visibile nella costellazione di Cassiopea.

Si individua nella parte orientale della costellazione, circa 1° a nordest della grande nebulosa IC 1805; il periodo più indicato per la sua osservazione nel cielo serale ricade fra i mesi di settembre e febbraio ed è notevolmente facilitata per osservatori posti nelle regioni dell'emisfero boreale.

Si tratta di una piccola regione H II facente parte di un trio di nebulose assieme alle vicine Sh2-193 e Sh2-194. Nella gran parte delle pubblicazioni si tende a considerarle come parte di un unico complesso, come nel Catalogo Avedisova, dove viene associato anche a tre sorgenti di radiazione infrarossa catalogate dall'IRAS; fra queste sorgenti vi è IRAS 02407+6047, coincidente con un ammasso aperto fortemente oscurato dai gas formato da almeno 50 giovani stelle, racchiuse in un diametro di 0,92 parsec.Sempre tramite questi studi emerge una distanza simile al Complesso W3/W4/W5, stimata attorno ai 2300 parsec (7500 anni luce),a cui sarebbero quindi associate.

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.
