20 stacked RAW DSLR images of the moon.
It took a while to convert the RAWs to TIFFs, a format Autostakkert!3 will accept, but it was worth it as this result is far superior to any stacked jpeg moon I've done. Then it took a while for AS to analyse the anchor point which was a tad worrying because it's this stage that has failed many times for me in the past. But it went smoothly. A slight sharpening of the stacked TIFF in Registax followed.
