Your latitude decides which constellations clear the horizon.
Optional — the bright stars in the frame get matched to a named constellation.

Run Identify on the Spot tab and your observing site, the photo match, and a write-up on each constellation overhead land here.
How the match is made
- Your coordinates fix the horizon — latitude rules out everything below it.
- The hour you pick rotates the sky; a constellation rising at 9pm has moved by midnight.
- A photo is matched on the pattern of its brightest stars, then named.
- Each named constellation comes back with where to look and a short write-up.
Do I need a photo?
No. Without one you still get everything above you at that hour, ordered by how easy it is to find.
My photo is blurry or mostly dark
Hand-held night shots often resolve only two or three stars. The report says so plainly and falls back to the overhead list for your site.
Where does "where to look" point?
Compass direction plus height above the horizon in fist-widths at arm's length — about 10° per fist.
