Here’s an old recording, processed with my new code:

Yes, as a matter of fact, I’m trying to clean it up and make it available. I’m also trying to work on an article for the AMSAT Journal that will detail how it works. Stay tuned!

Great web site, I will be interested in your developments and your code been available to try out.

Very impressive how the image is so clear from the original, been trying to improove my images and always grateful of any ideas.

Good luck and 73 from England.
