Description

***** ENG: The "Squid Nebula" in Chepeus only shows the red component in color. No chance to capture the green "Squid" even under the excellent sky of Colle dell'Agnello and reasonable exposure. SQM 21,6+, Bortle 2. This photo (IMHO) is an obvious demonstation that CCDs are still superior to DLSR when the game gets tough....

***** ITA: La nebulosa "Squid" in Cefeo mostra solo la componente rossa in luce integrale. Nessuna possibilità di catturare la componente verde senza filtro OIII, nemmeno dall'eccellente cielo del Colle dell'Agnello. SQM 21,6+, Bortle 2. evidente dimostrazione (a mio avviso) che i CCD sono ancora nettamente superiori alle DLSR quando i soggetti sono davvero difficili.
