Hi guys,
My brother is into geocaching where you use a GPS to locate markers (a bit of high tech hide and seek). There are hundreds of them across Australia and the world. Some give the location by puzzles or clues. Here's an astronomical one he drew my attention to. Here's the reference:

This one has the latitude and longitude hidden in the Messier No for these objects. I've worked out enough to confirm it is in a reserve not far from where the ASNSW meets and the AAO HO at Epping.
In case you wish to try the whole puzzle, I won't disclose what I have figured out so far except that the top line is the latitude and I'm struggling with the last 2 images. The bottom line, the longitude, I'm having trouble with the last image.
I'd like to give him the answer, any help?
Thanks
Glenn
