DescriptionMessier 31, The Andromeda Galaxy.jpg |
English: This is a cropped version showing the Galaxy Core right from center and NGC206 blue stars to the left. A total of 17.4 hrs integration time with Red, Green and Blue filters on QHY16200 CCD cooled to -20C attached to Esprit 100 f5.5 refractor. (209 subs of 300 seconds) Imaged on 10,11,12,14,15 & 16 Aug 2018.
There is a tiny white annotation showing the location of "The Star that changed the Universe", a Cepheid variable named "V1" by Edwin Hubble. He used V1 in 1923 to prove that the Andromeda "Nebula" was in fact a Galaxy outside our own Milky Way.
