Bravo Vesper! va decisamente meglio!!!! Sorriso

In nucleo per me è ok, forse se facevi una serie di esposizioni diverse, una per il nucleo e l'altra per la spirale sarebbe stato ottimo... la focale è stata 200mm o hai aggiunto il 2x? ma come hai focheggiato? io col mio non ci sono riuscito Sorry

Vesper Bravo! should definitely be better!! :-)
In core for me is ok, maybe if you did a series of different exposures, one for the core and the other for the spiral would have been great ... the focal length is 200mm or've added the 2x? but as you focheggiato? I did not succeed with my :-|

Hai assolutamente ragione sul fatto delle esposizioni!!! Il problema è che non sono capace e non so come si fa Sorry

non conosco la procedura... La focale? 200mm. Oltre a spostarmi di posto (meno illuminato) stavolta ho puntato anche su un altro fattore: ho cercato di mettere il più possibile andromeda al centro della lente per sfruttarne la qualità. Niente 2x. Per focheggiare ho puntato una stella luminosa e l'ho ingrandita a 10x con lo zoom digitale nel live view. Se vogliamo essere precisi e puntigliosi ti confesso che le stelle non sono a fuoco perfetto in questa foto, ma per fortuna si vede poco. MrGreen

You're absolutely right about exposure! The problem is that they are capable of and I do not know how to do :-| :-|:-D:-D I do not know the procedure ... The focal length? 200mm. In addition to move in place (less enlightened), this time I focused on another factor: I tried to put as much as possible andromeda at the center of the lens to take advantage of the quality. Nothing 2x. To focuse Put a bright star and I zoomed to 10x with digital zoom in live view. If you want to be precise and fussy I confess that the stars are not in perfect focus in this photo, but fortunately rarely seen. :-D

P.s. Se non lo conosci già e ti interessa, ti passo un link che spiega le procedure con photoshop per ottenere un fondocielo uniforme (a me è stato utilissimo in questi ultimi scatti). Ora purtroppo non posso perché sono fuori e sto da cellulare.

Ps If you do not already know and are interested, you step a link that explains the procedures with photoshop to get a uniform fondocielo (to me it was very useful in these last shots). Now, unfortunately I can not because I'm out and I'm by phone.

Ecco a voi!! Buona lettura :) www.astrofototecnica.it/Tecniche/elaborare-immagini-astronomiche-con-p (c'è da cliccare sul "qui" rosso per aprire il pdf)

P.s.: Non mi ero reso conto che potevo tirare fuori un po' più di segnale schiarendo un pochino sui valori tonali... Vabbè pazienza ... Se lo avessi fatto comunque si vedeva un pochino di più la forma ellittica ma al prezzo di renderla rumorosa e meno definita

Here's to you! Happy reading :) www.astrofototecnica.it/Tecniche/elaborare-immagini-astronomiche-con-p (need to click on the "here" red to open the pdf)

Ps: I had not realized I could pull off a little 'more than a little clearing signal the tonal values ??... Oh well ... patience If I did, however, you could see a little more of the elliptical but at the price of making it noisy and less defined

Scusa non ho capito cosa intendi... La guida è per fare delle modifiche su photoshop che gira tranquillamente anche su mac Cool

I'm sorry I did not understand what you mean ... The guide is to make changes on photoshop that can run also on mac 8-)

Hai ragione, mi sono perso un "free" per strada! MrGreen

Cercavo qualche programma freeware per l'elaborazione di foto astronomiche RAW, partendo da zero!

You're right, I missed a "free" in the street! :-D
I tried some freeware program for processing photos astronomical RAW, starting from scratch!

Con il fondo cielo troppo scuro purtroppo hai cancellato le bracci della galassia,ma per essere le prime la accettiamo,con esperienza capirai tante cose,a me piace davvero!!

With the sky background too dark unfortunately have deleted the arms of the galaxy, but to be the first to accept, with experience you will understand many things, I like really!

Grazie Skender, seguo sempre i tuoi stupendi post! Sono onorato :)

p.s.: Qualcuno ha suggerimenti su che altri oggetti potrei riprendere in questo periodo con questa attrezzatura? Sorriso

(soprattutto nei dintorni del nord, perché il giardino della casa in cui mi trovo è esposto lì)

Mi sa che stasera provo il doppio ammasso...

Thanks Skender, always follow your wonderful post! I am honored :)

ps: Does anyone have suggestions on other items I could take back this time with this equipment? :-)
(Especially around the north, because the garden of the house where I am is exposed there)

I think tonight I feel the double cluster ...

Grazie per la info ho memorizzato la pagina ;-)

Ha ragione Skender, ma essendo la tua prima piace anche a me....
A nord c'è ben poco purtroppo, a meno che usare un telescopio ... Eeeek!!!

Dacci dentro Vesper! MrGreen

Thanks for the info I bookmarked the page ;-)
He's right Skender, but being your first I like it too ....
To the north there is very little unfortunately, unless you use a telescope ... wow!

Give us inside Vesper! :-D

Bella, si vedono le nubi di polveri e per me che sono un visualista e che al massimo riprende la Luna è un bel vedere!

Bella, you can see the clouds of dust and for me as a visualist and that at most takes the Moon a pretty sight!
