Ho scelto il centro della Via Lattea (la galassia di cui il nostro Sole fa parte) per testare seriamente l'obiettivo Yashica ML 50mmf/2 risalente ai primi anni'80.

Non male la risposta cromatica e il coma radiale è trascurabile chiudendo il diaframma già a f/4.

Quella sera sui Nebrodi il cielo era discretamente trasparente, ma mi è sembrato di notare purtroppo un certo aumento dell'Inquinamento Luminoso in direzione SE e Sud.

Malgrado questo, ho voluto tentare a non utilizzare il filtro Astronomik CLS.

E' stato faticoso ridurre il non indifferente gradiente che influenzava negativamente oltre metà

del FOV proveniente dalla parte bassa a dx.

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.
