Description

**** ENG: after the July "session", being very satisfied with the image taken then (https://www.astrobin.com/zwx351/) I decided to dedicate the Colle dell'Agnello 2021 "astronomy camp" to shoot in more detail - and in color - the same subjects. Here is the first of the three (obviously the Veil). The HOO composition was retouched by my talented friend Edoardo Radice .

Not a very long exposure (3 hours in OIII and 3 in Halfa), but the result seems good to me, thanks to the good optics, the excellent sky of the Colle, and above all the extraordinary ZWO6200, which has practically zero noise, and therefore allows you to "pull" the curves a lot during the processing phase.

SQM 21,7-21,8 - Bortle 2/3

**** ITA: dopo l'uscita di luglio, essendo molto soddisfatto dell'immagine ripresa in quella occasione (https://www.astrobin.com/zwx351/) ho deciso di dedicare il campo osservativo del Colle dell'Agnello 2021 a riprese più in dettaglio - e a colori - degli stessi soggetti. Ecco la prima (ovviamente il Velo). Composizione HOO ritoccata dal bravissimo  Edoardo Radice .

Per una posa tutto sommato abbastanza breve (3 ore in OIII e 3 in Halfa) il risultato mi sembra buono, merito della buona ottica, dell'ottimo cielo del Colle e sopratutto della eccezionale ZWO6200, che ha un rumore praticamente nullo, e quindi consente di "tirare" molto le curve durante la fase di elaborazione.
