Notes/ Conditions |
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. |
