[OpenLayers-Users] Change Aspect Ratio of map without changing projection?

[Michael]

I am sure that there is a simple and quick answer out there.

My map is here:  http://pacificcup.org/OpenLayers/longpac.php

In creating geographically accurate circles on the map, it's become 
evident that the map has noticeable horizontal exaggeration at this 
latitude.  (The circles look like eggs).

What's the simplest way to adjust the X axis of my map while leaving the 
Y axis intact?  In other words, I wanna squish it.

I'm imagining (hoping) that it's just a css fix, but my efforts there 
have not been successful.

Thanks!

Michael
