Description

Walter Baade discovered this relatively dust-free view of the galactic core using the 100-inch Hooker telescope at Mt. Wilson in the 1940s. Previously, not much was known about the structure and location of the center of our galaxy. There are so many stars in this view!

I took a stack of images, but DeepSkyStacker I don't think is really built for this kind of data, and I didn't like the result. So I just spiffed up one of the subframes in Photoshop instead.
