Historical Sites on Shetland

I'm doing a Google MOOC about the mapping tools they provide - this map (which is for one of the assignments) shows a number of historical sites at the south end of the Shetland Mainland.

The mapping tools are very good - but the embed function doesn't appear to let me control where the map is centred (so it's under the info box - just drag the map to the right....)

And the embed stuff renders very strangely on a iPad too, not sure who's 'problem' this is.


This is what I'm trying to get the initial image to look like.
