In the eyepiece, forget to see something...
I would stand on an f4 and staking is absolutely necessary to reach hours of exposure Nell'oculare scordati di vedere qualcosa...
Io starei su un f4 e lo staking è assolutamente necessario per raggiungere ore di esposizione |

I agree with Pi Gi, but above all the focus in these cases must be precise and if possible motorized, precisely because our hand in addition to vibrations is not so precise, compared to an electronic sealer. Stacking is necessary as you need the flat darl and the biases for these deepSKY objects... I recommend if you haven't done so to see the automation program par excellence, Sequence Generator Pro... I use it and I control everything from the frame to the focus of the sealer, to the shot of the reflex... look here [IMG]3606562[/IMG] Concordo con Pi Gi, ma soprattutto la messa a fuoco in questi casi deve essere precisa e se possibile motorizzata, proprio perchè la nostra mano oltre alle vibrazioni non è cosi precisa, rispetto ad un focheggiatore elettronico. Lo stacking si è necessario come sono necessari i darl i flat e i bias per questi oggetti del DeepSKY...ti consiglio se non lo hai fatto di vedere il programma di automazione per eccellenza, Sequence Generator Pro...io lo uso e comando tutto dalla montatura alla messa a fuoco del focheggiatore, allo scatto della reflex...guarda qua www.juzaphoto.com/galleria.php?t=3606562&l=it
ti rimando al mio articolo magari può essere fonte di ispirazione

I have a question to the most scafatial astrophotographers...
Premissive:
-Fact except that to break down the digital noise resulting from the overheating of the sensor and the motion due to a non-perfect chase it is necessary to sum medium-short images compared to a long one.
-That all the images removed the flats and the dark portray the same scene and that are practically indistinguishable from the RAW.
Why take so many different images and not always integrate the same renamed n times to ensure a sufficient amount of signal?
Ho una domanda agli astrofotografi più scafati...
Premesse:
-Fatto salvo che per abbattere il rumore digitale derivante del surriscaldamento del sensore ed il mosso dovuto ad un non perfetto inseguimento convenga sommare immagini medio corte rispetto ad una lunga.
-Che tutte le immagini tolto i flat ed i dark ritraggano la stessa scena e che siano praticamente indistinguibili dal RAW.
Perchè scattare tante immagini diverse e non integrare sempre la stessa rinominata n volte da garantire un quantità di segnale sufficiente?

You would have the sum of the noise that instead changes position in all images being random and therefore you would have more noise than stars
The lights have to be taken with as much time as possible to store as much signal
I did not understand which images (excluding dark and Flat) are equal to the RAW. What do you mean by RAW? Si avrebbe la somma del rumore che invece cambia di posizione in tutte le immagini essendo casuale e quindi avresti più rumore che stelle
I lights devono essere scattati con il maggior tempo di posa possibile per incamerare più segnale
Non ho capito quali immagini (escluso dark e Flat) sono uguali al RAW. Cosa intendi per RAW? |

I was talking about what you call light.
I was looking for a "shortcut" to spend hours and hours with the telescope up there, even being able to snoop in the sky.
I noticed that in the capture, the first image (I use raw) was practically the same as the last... so why not simply duplicate the first or first instead of taking 20 or 30 to feed them to a stacker?
Parlavo di quelle che tu chiami light..
Cercavo una "scorciatoia" per no passare ore e ore con il telescopio all' insù seza neanche poter curiosare nel cielo.
Ho notato che nell' acquisire, la prima immagine (uso i raw) era praticamente uguale all' ultima... quindi perchè non duplicarle semplicemente la prima o le prime invece di scattarne 20 o 30 per darle in pasto ad uno stacker?

They look the same to you...
I'm all different with different information Sembrano uguali a te......
Sono tutte diverse con informazioni diverse |

... thankfully!
They is the result of study and a lot of patience and perseverance. If it were possible to do as you say in an evening you could make multiple subjects... but, in my opinion, with very little taste ...per fortuna!
L'astrofotografia è frutto di studio e tanta pazienza e costanza. Se fosse possibile fare come dici tu in una serata si potrebbero fare molteplici soggetti...ma, a mio avviso, con molto poco gusto |
