full moon in the sky

Full moon 128 images, aligned to 1/16th pixel and median blended. Then a 1.5 pixel sharpen (in photoshop). I'd previously aligned in photoshop but it wasn't great on some of the shots. And as I'm a software engineer (by day) I have written my own algorithm for alignment; so ended up using that. Took 3 days to run on all 128 images but at least the end result was perfectly aligned. In the photoshop version, a few frames didn't align so the resulting averaging was slightly smeared. I'm doing lots of moon shots as we're in lockdown for covid, so this was taken from my backyard.
