Hi Go to Google images and search "moon lens flare" you will see lots of images, many factors contribute to how a lens flare looks , construction of the lens ,lens coatings , angle of light to the lens etc etc.
There have been a few threads on here with UFO reports which were shown to be lens flare.
You have to remember the OP's picture was an ipad held near the eyepiece not an ideal situation for taking pictures
Here is a thread on the subject of flares but there are more.
From another thread read this post and the one below it
There is a lot to this subject and if you don't understand how it works you can be fooled.
