It really is hard to get a perspective on just how many stars there are in the Milky Way region of the Sagitta image. So I took a BIG crop out of the bottom of the image and magnified it by 4x to get the second image above. The second image is STILL jam-packed with stars, but it gives a slightly better idea of just how many stars we’re talking about.
The program Registar identifies 505,000 stars in the whole of Sagitta image, and my feeling that is pretty much a lower estimate.
