About this image

Based on my interpretation of the satellite image from Zoom-Earth I ignored the other weather forecasts and risked the journey to get some more observations. Squeezed 56 subs into the time available before the target moved behind trees. This stack is processed in Affinity photo separating and processing RGB signals with James Ritson v20 macros before recombining them.
