hello Can someone please clarify a point about Hubble's work?: By using cepheids Hubble showed that the so called "nebulae" were too distant to be contained within our galaxy. My question is the following: is it only with the buidling of the 100-inch telescope that they were able to resolve the "nebulae" into individual stars and so then focus on the cepheids? ie. before the 100-inch telescope, the other galaxies were too far away to resolve into individual stars which is why they were mistaken for nebulae. And to drive the point home - Was there any instance before the use of the 100-inch that individual stars could be resolved in other galaxies?
