Beautiful Antioch Paul, with all its extension and stellar density is blown out so much stuff. Just one question: how did they perform your 450D Baader? I with the same reflex (Baader Idas LPS + P2) to the maximum use 350 "with a 90" range because the sensor lot warmer and spite the added offsets it is hard a33333333333333333333333333333333333 contain the thermal noise during the processing even with the use of PixInsight ... you to use 21x600 "it definitely a cooling system or some trick that I do not know: -o ... my warmers as an iron and for this reason I was seriously thinking about a dSLR or even cooled Peltier a CCD camera as Sbig 8300c that has a thermal delta of -40 ° c and it uses the tried Kodak 8300 sensor
Bella lì Paolo in tutta la sua estensione e densità stellare, è saltata fuori tanta roba. Una sola domanda: come si è comportata la tua 450D Baader? Io con la stessa reflex (Baader + Idas LPS P2) al massimo uso 350" con un intervallo di 90" perchè il sensore scalda parecchio e nostante gli offsets aggiunti si fa fatica a contenere il rumore termico durante il processing anche con l'uso di Pixinsight... tu per usare 21x600" hai sicuramente un sistema di raffreddamento o qualche trick che io non conosco  ... la mia scalda come un ferro da stiro e per questa ragione stavo seriamente pensando a una dslr raffreddata Peltier o addirittura a una camera CCD come la Sbig 8300c che ha un delta termico di -40°c e che usa il collaudato sensore Kodak 8300

Hello Paul, I see the stars elongated guide you had problems? in my experience it could also be an approximate balance in AR ... but on the whole the picture is pleasant (a ful. res. you highlight a few small problems) unfortunately DSLR limits are right here ... not having the cooling the sensor :-(
A greeting
Riccardo ciao Paolo,vedo le stelle allungate hai avuto problemi guida? secondo la mia esperienza potrebbe essere anche un bilanciamento approssimativo in AR... comunque in complesso l'immagine è gradevole (a ful. res. si evidenzia qualche piccolo problemino)purtroppo i limiti delle DSLR stanno proprio qui... non avendo il raffreddamento del sensore
un saluto

Hello Beppe, thanks for the comment! No trick, the room is not cooled, and the only system that I use to reduce a little 'noise is dithering. Generally I try to do longer exposures to extract the weaker signal, but the noise of summer is felt.
@Riccardo Thanks for visiting. That's right, the stars are slightly elongated due to a balancing problem: the same evening I tried to make the first photos of ' "Eroica" by clicking with the refractor and driving with Newton 200. Having no desire to dismantle everything, removed SLR film I put digital at the place and the guider on the Newton, but the setup was too heavy and the stars were slightly elongated.
Paul Ciao Beppe, grazie per il commento! Nessun trick, la camera non è raffreddata e l'unico sistema che uso per ridurre un po' il rumore è il dithering. In genere cerco sempre di fare pose più lunghe per estrarre il segnale più debole, ma d'estate il rumore si fa sentire.
@Riccardo grazie per la visita. Esatto, le stelle sono leggermente allungate a causa di un problema di bilanciamento: nella stessa serata ho provato a realizzare prima le foto dell' "Eroica" scattando con il rifrattore e guidando con il Newton da 200. Non avendo voglia di smontare tutto, tolta la reflex a pellicola ho messo la digitale al posto e l'autoguida sul Newton, ma il setup era troppo pesante e le stelle sono rimaste leggermente allungate.

I have too much to learn .... for now better if I admire your poses, then we'll see.
Compliments.
Paul Ho troppo da imparare .... per ora meglio se ammiro le tue pose, poi vedremo.
Complimenti.
