Description

TESTO ITALIANO SOTTO

M101 with my 12" ODK and Canon 6D. Just 14 frames under a pretty good sky (Bortle 2-3, SQM 21,3). Note the huge difference between my post processing (B) and Edo's 's (original). Mine seems b/w but is maybe a little less noisy. Another try (final) is Edo' work with all the 40 raw frames taken that night, PLUS a Ha set taken by Edo with his CCD, WO-FT110+Ha in the URBAN sky near Brescia. So, this image is a collaboration between two telescopes, a DLSR and a CCD, and two friends. And a Galaxy, of course! But BRAVO EDOARDO, becasue he's the post-processing master....

M101 ripresa col mio DallKirkham modificato da 30 cm e Canon 6D sotto un cielo dignitoso (Bortle 2-3, SQM 21,3). Notare l'enorme differenza tra la mia elaborazione (versione "B") e quella di Edoardo Radice ("original"). La mia sembra in b/n ma forse ha meno rumore di fondo. La verisone "finale" invece, è la stessa immagine utilizzando però tutti i 40 frame realizzati quella notte, cui Edo ha aggiunto una sua ripresa in Ha, effettuata col suo Williamo Optics 110 da Castenedolo (BS). Insomma, una collaborazione tra due telescopi, una DLSR e un CCD e due amici. Con l'ausilio della galassia, ovviamente! :-) Tutti i complimenti a Edoardo, fautore della complessa elaborazione.
