Yoctox, grazie del commento!
Come dicevo in qualche altro messaggio, trattasi di un mero esercizio. Le foto sono altre (e raramente comprendono galassie a tutto cielo MrGreen)
Sì, sullo stacco tra cielo e terra ne parlavo giusto sopra...

Non capisco questa frase:
trasformazione in stelle del disturbo digitale

Il disturbo (poco, peraltro) è stato ridotto in Camera RAW oltre che tramite sottrazione di media di frame neri. Le stelle sono un'altra cosa. Forse alludi al fatto che siano colorate e quindi possano sembrare rumore. Il sensore della A7RII (come altri sensori moderni) permette di vedere i colori delle singole stelle, quando queste non siano troppo luminose da esser bruciate. Peraltro è il motivo per cui ho scattato "solo" a 1600 ISO e poi aumentato l'esposizione in postproduzione (così da sfruttare più gamma dinamica e bruciare meno stelle possibile). Quindi mi sono limitato ad evidenziare i colori già presenti, senza inventarne, né tantomeno trasformare il rumore in stelle. Nell'immagine a risoluzione piena (circa 9000x9000 pixel), qui non presente per ovvi motivi, credo la cosa sia più chiara. Una cosa che ho notato, peraltro, rispetto al sensore precedente, è che anche il blooming attorno alle stelle bruciate è molto contenuto e risulta essere dello stesso colore della stella a cui appartiene (una cosa inenarrabile, per me).

Thank you Michael, I appreciate your very good explanation. My phrase "star transformation of digital noise" referred to the fact that some clusters of points appear in light blue / light blue, apparently did not understand I've got a lot :)

Beautiful photos and incredible detail ... I see that the r2 sensor works well even at night.

Thank you! They are my first attempts. As a technique we can be. However, for together I plan to improve.

Compliments.
But I do not understand one thing: the a7r2 did not have the "star eater" problem?
With a single shot at 8 seconds how did you get a picture like that? I thought it would take a longer time

The star eater is there but it is a problem for the professionals. Red stars are small, not all stars. Here we talk about several united photos. No, you can not use a longer time in that situation. We are talking about a 35 mm lens on a 42-megapixel sensor in a sky area with a rotation that did not allow it to go up more than 8 seconds without having oval stars in that situation.

Thanks Michael, very interesting all your details. One last curiosity, if I can: how did you melt together the portions of heaven? I for architecture photos I used the merge command of photoshop but with a black sky with many dots I do not know if I would get a correct overlap of the portions of sky

I usually use PTGui. Many use Hugin.

Thank you! In hindsight I would do it in an extremely different way. But It was one of my very first approaches... Thank you very much
