Here's a quote and image from FB SpaceX group user Ross Sackett;
"I used a trick we sometimes use to fix the position of a star in an astrophoto(graphy.) While the fireball is burned into the image making it hard to locate the center, the lens flares (probably diffraction spikes) are centered on the brightest part. Make of this what you will.
This centers near an S bend in a large strongback (electrical?) conduit near the level of the common bulkhead in S2. There are other connections to S2 near there.
L2 SpXers sound like they're focussing on something, but will wait for Musk to pull the trigger publicly."
