I thought maybe the star field was Lupus, but it doesn't seem to match up. The triangles to the left are interesting. The compass to the top-right looks like it's sourced from the original Puerto Princesa map.
There is some sort of cracking going on in the bottom right that doesn't look like typical nebula artifacts.
Finally, here's the brightest stars pulled out after doing some image processing on the underlying image: http://imgur.com/S7yHjug

One thing I just thought of... it could be Lupus if it were skewed. Anyone have a constellation software that would show us what Lupus would look like, from Puerto Princesa, far into the futur?
