It fascinates me all this, I will never be able but I'm very attracted. From passionate to physics and astronomy then ... Mi affascina tutto questo, non sarò mai capace ma sono molto attratto. Da appassionato di fisica e astronomia poi... |

Thank you Renzo for the explanations.
So even if I make a change to my reflex with the baader filter every time I photograph an object that is not input on ir, i need to mount a uv-ir cut correction filter to get the actual colors right? Grazie Renzo per le spiegazioni.
Quindi anche se faccio una modifica alla mia reflex con il filtro baader tutte le volte che fotografo un oggetto che non sia ad immissione sull ir, devo montare un filtro correttivo uv-ir cut per ottenere i colori reali, giusto? |

I like Paul, for Ulk: If you modify your Baader camera you do not need the UV-IR Cut because the Baader filter has the specifications to expand the bandwidth to the IR so that it does not penalize the Ha, in fact cuts to ca 700nm (the Ha is 658nm); In case of light pollution, however, you have to put a specific filter on the optic (there are several CLS-CCDs, UHC-Ss, Idas Hutecs etc, and if you continue to use your camera even in daylight for normal photos, that you shoot only in RAW, then you can correct the light pink dominant without loss of quality with RAW Camera of Ps or SW similar, there is no need for corrective filters :-)
ps: If you use the Fuji you will surely have many satisfactions, it has an innovative quality sensor ;-) Mi fa piacere Paolo, per Ulk: Se modifichi la tua fotocamera Baader non hai bisogno dell'UV-IR Cut in quanto il filtro Baader ha le specifiche per ampliare la banda passante verso l'IR in modo da non penalizzare l'Ha, infatti taglia a c.a. 700nm (l'Ha è 658nm); in caso di inquinamento luminoso dovrai comunque mettere sull'ottica un filtro specifico (ce ne sono svariati CLS-CCD, UHC-S, Idas Hutec ecc.; inoltre, se continui ad usare la tua fotocamera anche di giorno per le normali foto, basta che tu scatti solo in RAW, poi puoi correggere la leggera dominante rosa senza perdita di qualità con Camera RAW di Ps o SW similari, non c'è bisogno di filtri correttivi 
ps: Se usi la Fuji avrai sicuramente molte soddisfazioni, ha un sensore innovativo di ottima qualità  |

Thank you Andrea for the dark: 3 poses from 450s and three from 900s, no flat, no bias; for the PP the speech would be too long to describe it exhaustively here, however, in great lengths, I used the basic procedures on Pixinsight and then I went to Photoshop CC for the composition of the two results of each shot and the treatment final cosmetic; the Astronomy Tools plugin for the stars and the denoise of the sky background was also very useful, but fundamental was the wise use of level masks to blend the bulge with the sunshine so as to keep the details in overexposed areas. I stop here because it's really difficult to explain it in a simple way, it certainly needs a great practice with software, processing is as important as capturing, sometimes even more ... :-) Grazie Andrea, per i dark: 3 pose da 450s e tre da 900s, nessun flat, nessun bias; per la PP il discorso sarebbe troppo lungo per descriverlo in modo esauriente in questa sede, comunque, a grandi linee, ho usato le procedure di base su Pixinsight e poi sono passato a Photoshop CC per la composizione dei due result di ogni ripresa ed il trattamento cosmetico finale; è stato molto utile anche il plugin Astronomy Tools per le stelle ed il denoise del fondo cielo, ma fondamentale è stato un sapiente impiego delle maschere di livello per fondere il bulge con l'alone in modo da mantenere i dettagli nelle zone sovraesposte. Mi fermo qui perchè è veramente difficile spiegarlo in modo semplice, di sicuro serve una notevole pratica con i software, l'elaborazione è importante quanto l'acquisizione, a volte anche di più... |

gorgeous . I do not even imagine what equipment is needed to allow this result to the D200 bellissima . Non immagino nemmeno quale attrezzatura sia necessaria per permettere questo risultato alla D200 |

Thanks for the positive comments Alessandro, I'm sorry for any delay in the response but I read only the notifications today, lately I'm very present on Juza for various commitments but I plan to resume as soon as the activity, right now I'm preparing to insert some photo :-P; as for the equipment you can see listed in the caption, nothing 'science fiction', just a discrete instrumentation in addition to the modified D200 (elimination of the lowpass filter) and a great patience in postproduction ;-) Congratulations on the beautiful portrait :-)
Best regards and welcome on Juza Grazie per i commenti positivi Alessandro, scusami per l'eventuale ritardo nella risposta ma ho letto solo oggi le notifiche, ultimamente sono poco presente su Juza per impegni vari ma conto di riprendere quanto prima l'attività, giusto adesso mi sto apprestando ad inserire qualche foto ; in quanto all'attrezzatura la puoi vedere elencata nella didascalia, nulla di 'fantascientifico', giusto una discreta strumentazione oltre alla D200 modificata (eliminazione del filtro lowpass) e una grande pazienza nella postproduzione Complimenti per il bel ritratto
Cordiali saluti e benvenuto su Juza |
