CRESCENT NEBULA - Nuova Elaborazione-Work In Progress E' da prima dell'estate che con Francesco Sferlazza proviamo a fare una ripresa decente di questo soggetto. Le difficoltà sono per lo più determinate dal fatto che riprendiamo da un cielo cittadino in provincia di Milano e raramente si trovano serate, con questo clima, che ci lascino guardare le stelle. E' work in progress ( forse ) perche' non abbiamo terminato di catturare tutto il segnale pianificato nel canale dell'ossigeno terzo e dell'idrogeno e l'elaborazione può risultare approssimativa . Speriamo di non doverci rassegnare ad archiviare questo lavoro assieme ad altri infiniti work in progress!:) i dati : telescopio TS100 montatura Avalon Linear Sensore Atik 383l Camera Guida QHY178III Filtro Ha da 3.5 nanometri Guida effettuata tramite OAG tempi di posa Ha 4 pose da 1 ora e 20 pose da 10 minuti OIII 11 pose da 1 ora RGB 60 minuti per ciascun canale Integrazione : Maxim + Photoshop

This is much better: the details are more pronounced and the background sky is more black and uniform color, also no longer see the whitish veil that you could see in the first photo.
Congratulations great job :-)

in any case I do not think would have been over-exposed.
The channel in which I took poses 1 is now the 'Ha (Acca Halfa) by
a filter that lets through only light in a window of only 3 nm
of a particular wavelength.

This chromatically is better but the other even though purple blue had a something special, more ethereal and soft focus 3d.

Yes, maybe you're right, this for the fact that I had differently dosed the stars of lesser intensity
confining more on background sky. In this, however, even the stars of lesser intensity have a presence
greater. But otherwise the two images do not compare. In the first there were really a lot of problems.

Sun thanks! :)
