Thanks A_mari89! That night I went up to the mountains to do some 'of astrophotography, then I noticed that the water was so firm (it was a night without a breath of wind) that the stars were reflected clearly and from there started the idea of ??the picture :-)
Greetings! Grazie A_mari89! Quella notte ero salito in montagna per fare un po' di astrofotografia, poi ho notato che l'acqua era talmente ferma (era una notte senza un filo di vento) che le stelle si specchiavano chiaramente e da lì è partita l'idea della foto 
Saluti! |

Congratulations, photos and wonderful collection. One question, why did you close the aperture by one stop of Samyang in this and in the other picture? A f2 do not satisfy the result? Complimenti, foto e raccolta meravigliosa. Una domanda, come mai hai chiuso di uno stop il diaframma del Samyang sia in questa che nell'altra foto? A f2 non ti soddisfaceva il risultato? |

Hello Simolucca,
The Samyang 12 is already very sharp at f2.0 but, in the case of astronomical photos, presents chromatic aberration that manifests as a purple halo around the brightest stars. Shoot at f2.8 allows me to reduce this problem, although it remains to be seen especially at the edges. Close more I ought not for reasons of excessive dilation of exposure times. f2.8 it seemed, a good compromise, but that does not mean to f2.0 lens is not a valid, anything, is a high-performance lens already in TA. Thanks for the comment and greetings! :-)
Alessandro Ciao Simolucca,
il Samyang 12 è già molto nitido a f2,0 ma, nel caso delle foto astronomiche, presenta aberrazione cromatica che si manifesta come un alone viola intorno alle stelle più luminose. Scattare a f2,8 mi permette di ridurre questo problema, anche se resta visibile soprattutto ai bordi. Chiudere maggiormente non mi conveniva per motivi di dilatazione eccessiva dei tempi di esposizione. f2,8 mi è sembrato, quindi un buon compromesso ma questo non significa che a f2,0 non sia una lente valida, tutt'altro, è una lente molto performante già a TA. Grazie per il commento e saluti!
