Thanks very much Alex appreciate it
Yes I’ve read various articles on “Drizzle”
You usually get a better outcome from “drizzling” if your either “dithering” or your undersampled
My pixel scale for the 6”f6 newt is 0.98 arc sec / pixel
My pixel scale for the 8”f5 newt is 0.88 arc sec / pixel
Therefore both are oversampled
I’ll give “drizzle” a try but my stars after 50% binning in Startools are nice and round with good resolution even when I zoom in a bit , they are definitely not blocky
