COLLABORAZIONE FRA ASTROFILI : M45 Con il mio amico Riccardo Sgaramella abbiamo deciso di unire i nostri light effettuati su M45 e devo dire che non è andata affatto male.Si tratta dell'unione di una serie di scatti fatto con ottiche diverse, da luoghi diversi ma quando c'è passione e tecnica si può fare tutto.Purtroppo lui le aveva riprese con un altra angolazione e quindi il master finale è stato dovuto croppare mantenendo bene al centro tutto l'ammasso.Questa mia elaborazione è stata eseguita per le fasi principali di rimozione gradienti e linearizzazione e starless (StarXTerminator) con pixinsight, poi tutta la fase successiva, e cioè Stretch ,calibrazione ed estetica con Photoshop.Alla fine ne è uscita una immagine da 20.3 ore😊Ecco i dati tecnici: Mirko: Montatura : Eq6 mod RowanOttica principale: W.O.

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.
