Why is the plane a circular band? Shouldn’t it be a roughly straight band viewed edge on? There’s something I’m not getting about the geometry of this synthesized image.

Is it possible to capture the entire plane of our galaxy in a single image? Yes, but not in one exposure: Maroun Habib did in two with some planning. Top and bottom part of this image were taken six months apart and there you have it, the complete plane buff.ly/2tDLYMy

Someone in the comments said that this is shot on a fisheye lens, in real life this band would be straight and above your head.

Artifact of projecting the curved celestial dome onto a flat image. Analogous to how every map lies about something to make a round earth legible
