Description

This was shot on the night of the 14th June 2023 in West London (Bortle 8.5). We get no astronomical night for about 3 months of summer in London but from about 23:30 to 02:30 it's dark enough for ultra-narrowband. This was a total of 40 5-minute subs (3 hours) at 3nm of each SHO on a Radian 61mm (275mm FL) sitting on an AM5. I run it with an ASIAir Plus and processed it in PixInsight, this is an HSO palette.
