Notes/ Conditions

 Conditions- Taking the lum conditions were very poor and guiding was erratic due to seeing and transparency. When taking the colour the moon was at 47% illumination causing  colours to become what muted.

There were severe gradients induced by the moons reflection entering the OT. Used PixinsightLe to reduce effect.
