In photo #2, do we witness eagles aloft in front of Sol's disk, or are they Sunspots?
Comparing both photos and considering the time lapse between them, I'd say that Max has caught Sunspots here...
Beautiful photos once again, Max! Thanks- AL
Both pics show the same spots, so no eagles, as there were 2 min between them. So they could be sunspots (or dirt on my lense)
Interesting article:
" Galileo and the Advent of the Telescope
The earliest astronomers had to rely on their eyes to observe the sun. Given the proper conditions (such as fog or haze or viewing the sun at sunset), it is possible to observe sunspots with the naked eye. Viewing the sun in this way presented a problem, since looking directly at the bright sun is not only hard to do, but very dangerous. You should never look directly at the sun. The sun's radiation contains not only visible light, but powerful ultraviolet radiation as well, which can severely burn your eyes and permanently damage your eyesight.
The invention of the telescope by Dutch craftsmen in about 1608 changed astronomy forever. Suddenly, European astronomers could peer into space, seeing previously unimagined details on known objects like the moon, sun, and planets, and discovering planets and stars never before visible."
