Conditions- Luminance frames were taken on the 16th as I finished off some colour on another galaxy. Moon had finally set., conditions had improved more than at the start of the night. Conditions on the 21st with moon @ 88% phase for the colour channels were quite good with a slight dew and seeing good. Due to moon, colours are a little muted.
