How to read this
- The image is the actual sky around your target, from NASA's Digitised Sky Survey.
- Red rectangle = what your camera will frame at the orientation shown. Everything inside ends up on the sensor.
- Green N + arrow = celestial north. The sky rotates around it; aligning your camera's "up" to this is the natural framing choice.
- Yellow dashed ellipse = the target's catalogued size. If it's bigger than the red rectangle, your gear is too zoomed-in to capture the whole thing in one frame.
- Scale bar = how big features are in arcminutes (60 arcminutes = 1°). The Moon and Sun are each about 30 arcminutes wide.
