About this image

First attempt to stack separate RGB filtered live stacks (4x5min for each colour) with L stacks (4x5min). I did not rotate the camera between colours and so there was considerable field rotation over the entire sequence meaning that the final image had to be heavily cropped as the telescope has an Alt/Az mount. Dark frames were subtracted automatically during stacking, but no flats were used. Alignment and stacking of separate live stacks and LRGB combining was all performed with Affinity Photo as was some slight post processing. This is essentially enhanced EAA.
