This is amazing! I have a background in physics and electronics, but I have never been involved in amateur radio. However, I would love to and would like to ask if one could point me to resources for delving into it? When it comes to math and e.g. electrodynamics and practical filters, I wouldn't need an introduction. Thanks!

Isn't it a copyright infringement to pick up some radio signal, reassemble it to pictures and publish them?
Written with tongue only half in cheek: Depends. In the US where media companies write copyright law and hand it to legislators, yes. In China where there appears to be no Rule of Law, no.

Communication with satellites in the US requires the highest level of amateur licensing called the Extra.

To experiment in radio on certain frequencies (like the ones needed to talk to satellites, requires a license from your nation's government, as radio frequencies are a shared resource. Certain levels of licensing is for 'amateurs' and other licenses are for more industrial things, like TV and what is commonly referred to as FM or AM radio. Communication with satellites in the US requires the highest level of amateur…
I'm now imagining the on-line radio amateur community poking fun at themselves when the recent slang interpretation of "extra" came along.
Earlier quoted context omitted.
I am not a native speaker, but it is my understanding that amateur has 2 definitions: 1) unpaid, 2) incompetent or inept. The Camras team is maintaining and operating the telescope on their own time. The members have dayjobs like programmers and scientists, or are retired professionals. So I'll go with the first definition.
unpaid as in never having done something as a paid profession. A professional software developer who retires and programs as a hobby is not suddenly an amateur developer.
