IC 1805

IC 1805 (nota anche come Nebulosa Cuore o con la sigla W4) è una nebulosa diffusa in associazione ad un ammasso aperto, visibile nella costellazione di Cassiopea, verso il confine con la Giraffa.È individuabile circa 6 gradi a sud-est della stella ε Cassiopeiae, ma si può individuare anche partendo dall'Ammasso Doppio di Perseo e spostandosi di circa 4-5 gradi in direzione nord-nord-est; fa coppia con un'altra vasta nebulosa, nota come IC 1848. Per poterla individuare occorre un telescopio con un grande diametro, non tanto per le dimensioni, dato che la nebulosa è abbastanza estesa, quanto per la sua debolezza. Una foto a lunga posa o una camera CCD rivelano invece l'oggetto con una certa facilità. L'intero complesso di nebulose visibili in quest'area si presenta circumpolare dalla gran parte delle regioni dell'emisfero boreale; i mesi migliori per la sua osservazione vanno da ottobre ad aprile.Continua la mia collaborazione con l'amico Emanuele Neri. Questa volta si tratta della famosa nebulosa cuore ripresa da lui da Cori in provincia di Latina ed elaborata da me con Photoshop e pixinsight.

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.
