Very beautiful ....
but is it normal for the shaletors to be curved inwards from both sides?
Or simply because of the wide-angle effect?
Thank you Molto bella ....
ma è normale che scie siano curvate verso l'interno da entrambi i lati?
O semplicemente è per l'effetto del grandangolo ?
Grazie |

Hello effedi, the effect of curvature is given by the distance from the polar, if in the frame there is the polar the "circles" are much more regular Ciao effedi, l'effetto della curvatura è data dalla distanza dalla polare, se nell'inquadratura c'è la polare i "cerchi" sono molto più regolari |

MIRKO , thank you for your response... it is clear what you say however my question was more specific to the fact that the curvature (even irregular) is not "one" but I see clearly "two" ... so that you can feel that there are two centers of curvature ... (one on the right and one on the left) really should there be only one not? (just the Polar)
Then obviously if the Polar ecenter everything is regular but if it was moved, the circles will look more like elissi but cmq all concentric always at one point! (no?)

it is undoubtedly understood that there are two points of rotation ...
boh I'm not an astronomer... maybe that's right! :-or :-D MIRKO , grazie per la tua risposta ... è chiaro quello che dici però la mia domanda era più specifica al fatto che la curvatura (anche irregolare) non è "una" ma ne vedo nettamente "due" ... così a percepire che ci siano due centri di curvatura ...(uno a destra ed uno a sinistra) in realtà dovrebbe essercene solamente uno no? (appunto la Polare)
Poi ovviamente se la Polare è in centro tutto è regolare però qualora fosse spostata, i cerchi assomiglieranno di più a delle elissi però cmq tutte concentriche sempre ad un solo punto! (no ?)
anche in questa: www.juzaphoto.com/galleria.php?t=581991&l=it
si intende senza dubbio che siano due i punti di rotazione ...
boh io non sono un astronomo... magari è giusto così !   |

I'm an amateur like you, too, the things I know for sure is that it depends on the Earth's rotation. If the polar is in the frame the circles are precise, if the polar is not framed this effect is created, which is normal, if you search star trail there are many photos like this. But the real reason I do not know, I hope that someone more experienced tell us because now I'm curious even I :)
Anche io sono un amatore come te, le cose che so per certo è che dipende dalla rotazione terrestre. Se nell'inquadratura c'è la polare i cerchi sono precisi, se la polare non è inquadrata si crea questo effetto, che è normale, se cerchi star trail ci sono molte foto così. Ma il motivo vero e proprio non lo so, spero che qualcuno più esperto ce lo dica perché ora sono curioso anche io :)
