See the real field of view
The overlay uses your telescope, eyepiece, or camera sensor. Check whether Andromeda fits in one frame, how Orion will look through a wide eyepiece, or which camera rotation works best.
Plan your astrophotography
Try different focal lengths and camera rotations, then decide whether the target fits in one frame or needs a mosaic.
