Real or Hoax? Photo of Large Flying Disc Over Washington

• When: June 11th, 2018
• Where: Des Moines, Washington
  
• What: Saucer shaped object photographed; Most likely a hoax

Someone gazing up at stars in Des Moines, Washington accidentally got a photo of  -  what looks to be - a giant flying disc (or saucer). The UFO was only noticed when the witnessed look at photos afterward, so it could be a strange camera anomaly or reflection, however I have never seen a "mistaken" photo like this before, so thought it was worth sharing (MUFON case 92688):

Captured image in picture. I did not see ufo at time of pic

I was out back of my house around 9 or 930 smoking a cigarette by myself. I took a picture of a star (which i do frequently) then i went inside. The next day when i was looking at my gallery in my phone i saw triangular circular object in the picture. I did not see the object at the time. There is a tree branch in lower right of pic. You can see patters on the object. Just really weird. I have picture on my phone with pictures taken before and after image.i just thought this might help you guys. I HAVE NOT ALTERED OR ADDED ANYTHING TO THIS PICTURE!.

What do  you think about this flying saucer photo? Could it be a hoax, a camera anomaly, misidentification,  or perhaps... an alien spaceship? Share your theories  below in the comments or on Facebook, Twitter, or Instagram.
