I have struggled with the Drizzle technique many years but had always problem to see any difference when taking images with my teleskop, shorter focal lenses has worked good. Now with faster computer, Windows10 64-bit and new updated software it works as I expected it from the beginning. The idea came already when I took my first digital astrophoto, the comet Hyakutake 1996. I read about NASA and how they use Drizzling on Hubble images to increase the undersampled images from it.
I have documented my workflow here and a first test with the Globular Cluster M13 as a test object.
My astrophotos with the telescope are taken from the balcony and never of very high quality, but this time it worked.
