Yeah, the colors!
I would not know where Polar is ... Già, i colori!
Io non avrei capito dove è la Polare... |

But that is not the Polar, which is almost exactly in correspondence with the celestial north pole Ma non è quella la Polare, che si trova quasi esattamente in corrispondenza con il polo nord celeste |

No the Polar is that, its coordinates are:
Straight ascension 2h 31m 48.7s
Declination + 89 ° 15? 51?
Instead the Polo has the coordinates:
Straight ascension ---------
Declination + 90 ° 00? 00?
So there is a big difference and in the picture you see, consider that the lunar disk is half a degree. No la Polare è quella, le sue coordinate sono:
Ascensione retta 2h 31m 48,7s
Declinazione +89° 15? 51?
Invece il Polo ha le coordinate:
Ascensione retta ---------
Declinazione +90° 00? 00?
Quindi c'è una bella differenza e nella foto si vede, considera che il disco lunare misura mezzo grado. |

Without shooting data it is not easy to orientate, to get a picture like that, with that polar offset from the center of the pole, you will have used a very very strong focal point, between 600 and 800mm, and a series of shots of at least 6 hours .
Without reference points and without shooting data I made an incorrect evaluation Senza dati di scatto non è facile orientarsi, per ottenere una foto del genere, con quello scostamento della polare dal centro del polo, avrai utilizzato una focale davvero molto spinta, tra i 600 e gli 800mm, e una serie di scatti di almeno 6 ore.
Senza punti di riferimento e senza dati di scatto ho fatto una valutazione errata |

Of course, it was made with an EF 300 f / 4 and 2x croppata, so as if it were 600, they are almost 12h of pose made during the winter solstice Certo, è stata fatta con un EF 300 f/4 e croppata 2x, quindi come se fosse 600, sono quasi 12h di posa fatti nel periodo del solstizio d'inverno |
