Get higher resolution project

Hi,
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.

I have written down details of my workflow if someone find it intersting.

It's very interesting technique. I will now do test on my old astrophotos, they are all taken with Dithering and my normal preprocessing is always demosaicing.

Very surpised how fast DSS Drizzle the images. Earlier it could take several hours, now only minutes. Maybe it cheat :-)
