Yes, I know - sometimes even in real life it is very difficult to
separate useful info from noise :).

Really interesting and unexpected - in general even with such low
resolution image looks smoothly. The noisy sources sometimes produces
very impressive effects - in this particular case it reminds me old VHS
fantastic movies, something like "Spiders from Mars" or "War of the
Worlds" (see attached image with post-production effect :)).

Looking forward to look at your future investigations.
