Hello, I was recently taking some images of the night sky when I noticed a really bright star (not sure about that) It was the brightest thing in the sky (except for the passing airplanes) and in the image, I found 2 thin/small streaks on each side of that bright object, could anyone help in identifying what it is?
It's hard to tell without any obvious points of reference. I use Stellarium to identify objects in the sky. You can run it back to the date/time of your photo in your location to see the night sky. It helps if you remember the general direction your lens was pointed. It also helps to to where it was positioned in the sky, such as relative to any constellations since Stellarium can also display those for you.
Given the 6 second exposure I doubt it was the ISS, satellite or plane. I believe they would have enough movement to notice in the image.
I used 4/19 at 9:24PM from your photo with Denver as the location to produce this screen capture - not sure about your DST setting. For planets, Mars was in the southeast sky, Saturn was not yet visible to the southeast, and Jupiter was in the west. The brightest stars are also labelled for you.
