Comment: Mousing over the photo shows the Cepheid Variable star that in 1923 Edwin Hubble used Henrietta Leavitt's
technique to determine the distance to the Andromeda Galaxy proving that it was not a nebula in the Milky Way but its own galaxy.
This greatly expanded the known size of the universe.
This image is almost the full frame of the Esprit 100 at 554mm with the APC-C chip size of the camera.
