I noviluni di questa estate non sono stati molto favorevoli. Spesso sereno ma con il cielo veramente poco trasparente. Inoltre anche la temperatura ambiente ha contribuito a complicare le cose per chi utilizza le DSLR non raffreddate.

Infatti in questa circostanza pur essendo a 1600 metri slm la temperatura non è mai scesa sotto i 20°C facendo lavorare il sensore della mia 550D intorno ai 26°-27°C e file.raw con rumore termico.

Ad ogni modo ho tentato di ottenere il massimo dall'immagine combinata con DSS.

Persino il gradiente da inquinamento luminoso ha voluto complicarmi la vita, ma spero che il risultato sia comunque gradevole.

The new moon this summer were not very favorable. Often without clouds but with very little transparent sky. Also, the ambient temperature has contributed to complicate matters for those who use DSLR uncooled.

In fact, on this occasion despite being at 1600 meters above sea level, the temperature never dropped below 20 ° C making the sensor work in my 550D around 26 ° -27 ° C and file.raw with thermal noise.

Anyway I tried to get the most from the image combined with DSS.

Even from light pollution gradient wanted complicate my life, but I hope that the result is still pleasant

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.
