You can well say that! Pretty exciting. Great result! But really only 20 seconds?? Or is it a mistake? Puoi ben dirlo! Parecchio entusiasmante. Ottimo risultato! Ma davvero solo solo 20 secondi?? O è un errore? |

Thank you :-) . I confirm the 20 seconds, I use an lx3 minitrack and with those focal lengths they are already past the recommended times. I believe that with my equipment room for improvement there may be looking for less polluted sites (the photo I made in the city, bortle sky 7) and studying some specific software. Grazie . Confermo i 20 secondi, utilizzo un minitrack lx3 e con quelle lunghezze focali sono già oltre i tempi raccomandati. Credo che con la mia attrezzatura margini di miglioramento possano esserci cercando siti meno inquinati (la foto l'ho fatta in città, cielo bortle 7) e studiando qualche software specifico. |

I mean, is it just a 20" picture?? Or are more 20 shots integrated? Anyway I think with a tracker (unless you put too much weight on it) the minute goes through it with ease. In any case, I think the signal-to-noise ratio is exceptional! Cioè è una sola foto da 20"?? Oppure sono più scatti da 20 integrati? Comunque penso che con un inseguitore (a meno di metterci troppo peso sbilanciato) il minuto lo superi con facilità. In ogni caso il rapporto segnale/rumore mi pare eccezionale! |

Sorry... I didn't understand. That's 199 20" shots plus 40 darks, 40 flats and 40 biases. As for the weather, at 400mm I don't know if there are "field" trackers that guarantee you a minute of exposure, but I'm still pretty ignorant on the subject Scusa... non avevo capito. Sono 199 scatti da 20" più 40 darks, 40 flats e 40 biases. Per quanto riguarda il tempo, a 400mm non so se ci sono inseguitori "da campo" che ti garantiscano un minuto di esposizione, ma sono ancora piuttosto ignorante in argomento |

Aaah ok, now it's all clear :-D that's where the great SNR comes from!!
As far as time and focal point is concerned, for the Pleiades I think that already 200/250mm (equivalent) is enough and allow you to definitely have more than 1 min for each subframe (at most croppi a little bit the final file). I have the star adventurer and with a 135mm mounted on an APS-C sensor, so 202 mm equivalent, I do 4 min without the slightest problem; I have not tried more but I think you can, if the weights are less than those supported and well balanced, there is no problem. Of course, you can't think of shooting from 600"... I don't know the minitrack, but I don't think it changes much.
Aaah ok, ora è tutto chiaro ecco da dove arriva l'ottimo SNR!!
Per quanto riguardo il tempo e la focale, per le Pleiadi penso che già 200/250mm (equivalenti) siano sufficienti e ti permettono di avere sicuramente più di 1 min per ogni subframe (al massimo croppi un po' il file finale). Io ho lo star adventurer e con un 135mm montato su un sensore APS-C, quindi 202 mm equivalenti, faccio 4 min senza il minimo problema; non ho provato di più ma penso si riesca, se i pesi sono minori di quelli supportati e ben bilanciati, non c'è alcun problema. Certo, non si può pensare di fare riprese da 600"... non conosco il minitrack, ma non penso cambi molto.

For the minitrack it is recommended to divide 100 by the focal length (equivalent FF), although with a very accurate polar alignment it seems that we can go further. I really like the star adventurer, but for now I still have to figure out what to invest money on. For example, I understand that a program like pixinsight (quite expensive) can have a lot of impact on the end result. Per il minitrack si consiglia di dividere 100 per la lunghezza focale (FF equivalente), anche se con un allineamento polare molto accurato sembra si possa andare oltre. Lo star adventurer mi piace molto, ma per adesso devo capire ancora su cosa investire denaro. Per esempio mi sembra di capire che un programma come pixinsight (piuttosto costoso) possa incidere parecchio sul risultato finale. |

A result to applause, dear Alan! Un risultato da applausi, caro Alan! |
