I wanted to integrate a lot more, but between bad weather and work commitments I did not find a suitable evening to resume in a deeper way this great Nebula.
The image, very dry, resumes the Veil Nebula in Narrowband Ha (about 2 hours) and OIII (another 2 hours or So) on a Nikon 300 2.8.
Some hour in RGB closes the shot to give the right color to the image Avrei voluto integrare parecchio di più, ma tra brutto tempo e impegni lavorativi non ho trovato qualche serata adatta per riprendere in maniera più profonda questa grande nebulosa.
L'immagine, molto secca, riprende la nebulosa Velo in banda stretta Ha (2 ore circa) e OIII(altre 2 ore circa) su un nikon 300 2.8.
Qualche oretta in RGB chiude la ripresa per dare il giusto colore all'immagine
La nebulosa è un residuo di supernova antica scoperta da Herschel alla fine del diciottesimo secolo.
La stella che ha originato la nebulosa probabilmente si trovava a 1000-2000 anni luce da qua ed è esplosa qualche millennio fa (8000?-1000? anni addietro ), vista la grande dimensione della nebulosa
I residui sono molto deboli, visto che il gas si sta espandendo velocemente da molti anni
La colorazione ciano dipende dal gas Ossigeno ionizzato, mentre la rossa deriva da Idrogeno ionizzato |

Another beautiful image Stefano!!! Of this remnant of supernova I love the faint inner strands... they are not easy to stand Out. Great!! ;-) Altra bellissima immagine Stefano!!! Di questo resto di supernova amo i deboli filamenti interni...non sono semplicissimi da far risaltare. Grande!!  |

Thanks Slashleo and Nicole
confirm, The central streaks are sharply weaker than the Edges.
The edges are also visible by telescope, in visual, perhaps with an oiii filter.
The central parts are really very weak Grazie Slashleo e Nicole
Confermo, le striature centrali sono nettamente più deboli dei bordi.
I bordi sono visibili anche a telescopio, in visuale, magari con un filtro OIII.
Le parti centrali sono davvero molto deboli |

Beautiful field... Finally I can appreciate its completeness!
Hello
Gp Bellissimo campo...finalmente riesco ad apprezzarne la completezza!
Ciao

Thanks GP!
is so big that it is difficult to understand the true shape of the bubble (actually extends even further, I would have to make a mosaic to take it All) Grazie GP!
è talmente grande che si fa fatica a capire la vera forma della bolla (in realtà si estende anche oltre, avrei dovuto fare un mosaico per prenderla tutta) |

Beautiful! And thanks also for the scientific explanation, very rare usually. Bellissima! E grazie anche per la spiegazione scientifica, molto rare di solito. |

Very nice :-) What filters did you use for Ha and oiii?
is the room modified? molto bella che filtri hai usato per Ha e OIII?
la camera è modificata? |

Thanks Daomao
The filters are astronomik with 6NM band
The camera is not a photo camera but a cooled CCD for astronomical use
with a reflex it takes a lot more exposure to get the same depth of image Grazie Daomao
I filtri sono astronomik con banda 6nm
La camera non è una macchina fotografica ma una CCD raffreddata per uso astronomico
Con una reflex ci vuole parecchia più esposizione per ottenere la stessa profondità d'immagine |

Thanks for the reply, do you think it would make sense to modify an unused d3300?
I have seen that in many change it to Super UV-IR cut and Full Spectrum (teleskop Express makes a lot of changes) grazie per la risposta, secondo te avrebbe senso modificare una d3300 inutilizzata?
ho visto che in molti la modificano per super UV-IR cut e full spectrum (teleskop express fa un sacco di modifiche) |

It makes sense
is the first step to do, much cheaper than venturing into the CCD specific cameras for astronomy
The yield is still discreet, it just takes a little more patience to get the result Si ha senso
è il primo passo da fare, molto più economico che non avventurarsi nelle camere ccd specifiche per astronomia
La resa è comunque discreta, ci vuole solo un po più di pazienza per ottenere il risultato |

That is Stefano, have you connected a CCD camera to a Nikon telephoto lens? and the filters? You can list all the optical chain with also the various adapters, please? Cioè Stefano, hai collegato una camera CCD ad un teleobiettivo Nikon? E i filtri ? Puoi elencare tutta la catena ottica con anche i vari adattatori, please ? |

Hi Mark
The CCD camera is a Moravian G2 8300FW
The wheel holder is inside the camera
the required draught is significantly lower than the Nikon optics so with a simple mechanical adaptor you can use all the optics For attack F (sells it directly Moravian)
Filters are those of the astronomik by 31.8 unmounted Ciao Marco
La camera CCD è una Moravian G2 8300FW
La ruota porta-filtri è interna alla camera
il tiraggio richiesto è nettamente inferiore a quello che hanno le ottiche nikon quindi con un semplice adattatore meccanico si possono utilizzare tutte le ottiche per attacco F (lo vende direttamente la Moravian)
I filtri sono quelli della astronomik da 31.8 unmounted |
