A great time of integration! Yes there will still be traces to recover. How did you stretch? On separate RGB channels or all together? Magari you could also try stacking on Siril, it allows you to better refine the file before proceeding with PS Un gran bel tempo di integrazione! Sì ci saranno ancora delle tracce da recuperare. Come hai effettuato lo stretching? Su canali separati RGB o tutti insieme? Magari potresti anche provare a fare lo stacking su Siril, ti consente di raffinare meglio il file prima di procedere con PS

yes, several hours; having a dslr not mod. I thought I'd step a little bit on the total time. I did stretching on all channels together, in photoshop. thanks for the suggestion, in fact I was thinking about it. I have already accrocchiato with some commands in siril, but the stacking I have not yet tried. I have 3 or 4 astro subjects taken in these days that I will rap graphically speaking in the hope of getting a spider out of the hole :-D 8-) who wins the hard! ;-) sì, parecchie ore; avendo una dslr non mod. ho pensato di pestare un pochino sul tempo totale. lo stretching l'ho fatto su tutti i canali insieme, in photoshop. grazie del suggerimento, in effetti ci stavo pensando. ho già accrocchiato con qualche comando in siril, ma lo stacking ancora non l'ho provato. ho 3 o 4 soggetti astro ripresi in questi gg che violenterò graficamente parlando nella speranza di cavare un ragno dal buco chi la dura la vince !

The Pleiades are always beautiful to see. I would have expected a little more nebulosity with all that integration. I find only a few details in the nebula, maybe you gave a heavy hand of noise reduction filters? Around Merope there is an intricate web of nebulosity, but I notice only 3 or or 4 main stripes. Le Pleiadi sono sempre belle da vedere. Mi sarei aspettato un po' più di nebulosità con tutta quella integrazione. Trovo solo pochi dettagli nella nebulosa, forse hai dato una mano pesante di filtri per la riduzione del rumore? Intorno a Merope c'è una ragnatela intricata di nebulosità, ma noto solo 3 o o 4 strisce principali.

I agree with you, Valerio. I'm trying and trying again, but I can't get more; I certainly did something wrong, maybe already in the acquisition phase :-( I'll do one more test without eliminating the noise eventually, thanks x the suggestion ;-) I have the impression, however, that being an original room, not modified, it has a limit that does not allow me great elaborations. concordo con te, Valerio. sto provando e riprovando, ma non riesco ad ottenere di più; ho certamente sbagliato qualcosa, forse già in fase di acquisizione farò ancora una prova senza eliminare il rumore eventualmente, grazie x il suggerimento ho l'impressione, però, che essendo una camera originale, non modificata, abbia un limite che non mi consente grandi elaborazioni.

On the Pleiades there is no big difference between a standard camera and a modified one. I think the problem may be in the post-production phase. DSS I do not like very much, I had prepared this video for my students in which I explain another free program that offers better results in my opinion. You can find it here: Sulle pleiadi non c'è grande differenza tra una fotocamera standard e una modificata. Penso che il problema possa essere in fase di postproduzione. DSS a me non piace molto, avevo preparato questo video per i miei allievi in cui spiego un altro programma gratuito che offre risultati migliori a mio avviso. Lo trovi qui:

installed, seen your tutorial and tried. unfortunately can't align the images. once I select all the images, I click on Process and I get a dialog box with "all dark frames and other selected frames must be the same size and their color type must match the selected image set process type. display the list of dark frames with different color type?" yet the images I selected are those taken that same evening with the same setup :-( I forgot something? installato, visto il tuo tutorial e provato. purtroppo non riesce ad allinearmi le immagini. una volta selezionate tutte le immagini, clicco su Process e mi esce un dialog box con scritto
"all dark frames and other selected frames must be the same size and their color type must match the selected image set process type. display the list of dark frames with different color type?"
eppure le immagini che ho selezionato sono quelle scattate quella stessa sera con lo stesso setup ho dimenticato qualcosa?

Hello Serafino, first of all happy new year! Compliments for the very interesting attempt. As a non-expert in Deep Sky photography, I would also say that I would have expected more nebulosity. Then the brightest stars have the burnt "core", that is, the Airy disks are saturated so that you see the secondary maxima but the central peak is as if saturated at full scale. I do not know if this is already in acquisition or in post processing (stretching?), but at least I do not like the final effect very much ... Apart from that the result remains as very pleasant. Hello, Daniele Ciao Serafino, innanzitutto buon anno! Complimenti per il tentativo molto interessante. Da non esperto di fotografia Deep Sky, direi anche io che mi sarei aspettato più nebulosità. Poi le stelle più luminose hanno il "nucleo" bruciato, ovvero i dischi di Airy sono saturati in modo che si vedono i massimi secondari ma il picco centrale è come saturato al fondo scala. Non so se questo sia già in acquisizione oppure in post processing (stretching?), ma almeno a me l'effetto finale non piace molto... A parte questo il risultato rimane come molto gradevole. Ciao, Daniele

thank you, Daniel; best wishes to you and family :-) :-) therefore of being quite denied, as well as with post processing, also with the acquisition :-( 3 min are probably too many, the stars are actually too big. I'm trying again to resume lowering times and ISO. let's see how it goes grazie, Daniele; tanti cari auguri anche a te e famiglia temo di essere abbastanza negato, oltre che col post processing, anche con l'acquisizione 3 min probabilmente sono troppi, le stelle sono effettivamente troppo grandi. sto provando nuovamente a riprendere abbassando tempi e ISO. vediamo come va

Hello Serafino, thank you very much for the good wishes! ;-) I don't think you're denied at all, in fact I think it's just a matter of finding the right recipe and then you'll go great as with planetary shots! 8-) According to me (but I repeat I'm not an expert in Deep Sky photos) since your chase holds up very well the 3 minutes, it makes no sense to reduce the exposure time. Rather I would lower the ISO until the seven sisters are burned. At that point you should have a great starting point for post processing! Keep up to date on your trials and progress! Hello, Daniel Ciao Serafino, grazie mille per gli auguri! Non penso affatto tu sia negato, anzi credo che sia solo questione di trovare la giusta ricetta e poi andrai alla grande come con le riprese planetarie! Secondo me (ma ripeto non sono un esperto di foto Deep Sky) visto che il tuo inseguimento regge benissimo i 3 minuti, non ha senso ridurre il tempo di esposizione. Piuttosto abbasserei gli ISO finché le sette sorelle non vengono bruciate. A quel punto dovresti avere una ottima base di partenza per il post processing! Tienici aggiornati sulle tue prove e sui tuoi progressi! Ciao, Daniele

I agree with Daniele, I also think that the fact that the brightest stars have swelled so much is the fault of the chromatic residue of the canvas you used. Concordo con Daniele, penso anche che il fatto che le stelle più luminose si siano gonfiate così tanto sia colpa del residuo cromatico del tele che hai utilizzato.
