30 x 10 min subs using a Ha narrowband filter. Data collected over a span of three weeks due to weather conditions. I originally had OII and SIII data but it was too weak and noisy due to intense light pollution here in Hong Kong, so I just kept the strong Ha data and assigned it to the blue channel.
I used an SBIG ST 8300M camera with a Ha filter on a Williams Optics 80mm refractor telescope.
