I am thankful for the unseasonable weather and imaging i have getting.
This is shot with my super high speed camera. If you pay attention to the sunspot penumbra you will see a little worm like appendage retreating into its core. Also notice the pulsating center.
Captured at 500fps.
and the rest of the film captures that larger fibril get sucked back down the drain. .

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 come 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.
included some images of April 12th.
One image of Vallis Alpes, witht he large craters Arsitoteles and Eudoxus.
Rima Hyginus, with lower in the image Triesnecker and Rimae Triesneckes to the right of it.
The Apennines. A large mountain range. This is a two panel mosaic.
and last byt not least a high res image of the lunar terminator from the Large crater Ptolemaeus all the way to the South pole.
All images made using CFF CC300 f/20 and asi 174MM at prime focus. An Astronomik proplanet 807 filter was used to stabilize seeing.
Enjoy the images, and feel free to share your toughts, comments etc. All images are also visible on my Astrobin page.
