ORIGINAL (final):
This Animation (13 MB) linked a image, taken in January 2005 with the Advanced Camera for Surveys aboard the NASA/ESA Hubble Space Telescope (Credits: NASA, ESA, and the Hubble Heritage Team [STScI/AURA]) and my new C14 LRGB-Image from March/April 2023 (
Whirlpool Galaxy (LRGB, Messier 51, 2023) ( Henning Schmidt ) - AstroBin). Good to see is the orange star in the lower left corner, which has moved significantly over the course of 18 years.
REVISION E:
Another moving star can be seen in revision E or in the mouseover (9 MB-Animation). I think the two moving stars are part of our Milky Way galaxy. Interestingly, they have the same direction of movement.
REVISION F:
More location-changing stars (in all directions) can be seen in this fade.
For this comparison I have selected an even older image from the 60 inch telescope of the Mont Wilson Obersevatorium, which was published in the observatory's 1915 Decade of Activity Report of the Carnegie Institution of Washington:
https://archive.org/details/carnegieinstitut235carn/page/63/mode/1up?view=theaterThe picture must have been taken there between 1906 and 1915, more than 100 years ago.
What do you think of this stellar movements?
