Description

This is Messier 100 (M100, NGC 4321). It's a grand design intermediate spiral galaxy. M100 is about 55 million light-years away from Earth. It’s about 107,000 light-years in diameter. I counted at least 17 additional galaxies in this image. I imaged this over 5 nights. I collected almost 20 hours of subframes. I ended up discarding a large portion of subframes due to poor seeing, poor tracking, and poor focus. In the end, I integrated 12 hours and 20 minutes of subframes.
