Attraverso la tecnica dell'HDR è stato possibile desaturare il nucleo, in modo da non avere zone bruciate. Infatti sono stati fatti 3x120 sec per il nucleo e 18x420 sec per il segnale debole delle stelle esterne. Ho usato il Tecnosky 80/480, quindi ho preferito croppare l'immagine per far risultare meglio l'ammasso Canon 450D modificata. I have taken 3x120 sec for the core and 18x420 sec for the weak signal of the external stars. I used the Tecnosky 80/480, so I preferred to crop the image to see better this DSO Canon 450D modified.

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. |
This image cannot be submitted for the IOTD/TP consideration.
