M100 lies in Coma Berenices and is a nearly face on spiral galaxy. Although one of the brighter of Coma's spirals, the range of brightness in the arms make it difficult to photograph well. It lies about 40 million light years away. To the right of the image, in line with the bright star and the same distance beyond it as it is from M100, is a blueish smudge. This is the elongated galaxy NGC4312. Very close to and slightly down from left of M100 is the much smaller and fainter NGC4322. Slightly further away and straight down from M100 is NGC4328.
