as a first attempt nn is not bad at all! I would recommend you do long exposures less and raise the ISO so should you delete frames nn you remain huge gaps between the wakes! 8-) come primo tentativo nn è affatto male! ti consiglierei di fare esposizioni meno lunghe e alzare gli iso così nel caso dovessi eliminare dei fotogrammi nn ti rimarrebbero buchi enormi tra le scie!

Thanks Matthew! :) I know it is better to take many more photos from 30-60s on one another iso values ??high enough, but I opted to preserve as much as possible the shutter because I was not sure of the result that I got. It must be said that with the exposure too long we encounter the problem of noise "heat" (hot pixels, etc. ..), but given the very low temperature and the sensitivity to 100 ISO this was very limited. The hole in the strip is due to the fact that the first was a test shot to check the thermal noise exposure and stars, then the next (the good ones) are left with a bit 'late, I should add it to the other but all in all I did not mind the result. Thanks again to the next step and star trails! :-P Grazie Matteo! :) So che è preferibile scattare molte più foto da 30-60s l'una a valori iso abbastanza elevati, ma io ho optato per preservare il più possibile l'otturatore visto che non ero sicuro del risultato che avrei ottenuto. C'è da dire che con le esposizioni troppo lunghe si va incontro al problema del rumore "termico" (hot pixel ecc..), ma data la temperatura molto bassa e la sensibilità a 100 iso questo è stato molto contenuto. Il buco nella strisciata è dovuto al fatto che il primo è stato uno scatto di prova per controllare rumore termico esposizione e stelle, quindi i successivi (quelli buoni) sono partiti con un po' di ritardo, non avrei dovuto unirlo agli altri ma tutto sommato non mi dispiaceva il risultato. Grazie ancora del passaggio ed al prossimo star trails!!

okay you understand what you've done! cmq another observation, if the next time get up the iso to 1600 will also see that there will be many more trails, make the photo more "attractive" 8-)
see you soon! Matthew ;-) si okay capisco quello che hai fatto! cmq un'altra osservazione, se le prossime volte alzerai gli iso a 1600 vedrai anche che ci saranno molte più scie,renderà la foto più "accattivante!"
