I did a photo of the night sky and wanted to find a constellation on it. I've suggestion that it is Delphinus constellation. Could you please help me figure it out. Also, I'm curios about good way to figure out constellations on a photo.

    $\begingroup$ aahhh the Pleiades are lovely. Do you see the blue tinge around them in your photo? That's the nebulosity from dust reflecting the light of the blue stars $\endgroup$

    $\begingroup$ I think when asking such questions, it would be helpful to know place, time and direction. Still some specialists can tell without knowing that. $\endgroup$

The object inside the red circle is indeed The Pleiades. Note that it is not a constellation, it is an open star cluster located in the constellation Taurus.

A good way to identify constellations in a photograph is to use the Astrometry website, where you can upload a photograph of the sky and the application searches for the constellation it belongs to.

    $\begingroup$ thanks for the answer! I tried Astrometry, it unfortunately didn't recognise the photo $\endgroup$

    $\begingroup$ It's also considered an asterism -- a recognizable formation smaller than a constellation. $\endgroup$

    $\begingroup$ @pacman for "fun" you might try to crop just the cluster itself and re-run it in Astrometry. I've never had any success with that site, ever, but I've always tried large areas of the sky from a handheld camera or similar, and I think it's primarily a "plate solver" meaning used for images taken through telescopes (i.e. small fields of view). Also just for "fun" How (the heck) does Astrometry.net work? which seems to suggest that other people DO have success with wide angle photos, just not me :-) $\endgroup$

These are the Pleiades. I verified it comparing your photo with the Stellarium app.
