A Big Telescope

I drove up to the VLA late this morning. Seeing one of these dishes up close is impressive and I was glad to discover they have a visitor center at the site along with the opportunity to get close to a dish.

These are of course radio telescopes and the VLA can be arranged in multiple configurations, the dishes get moved by a dual railway system. In one configuration using interferometry, the system can resolve the resolution equivalent to a 20 mile dish!

It was a lot of fun to visit; also parts of the movie Contact (one of my favourites) were filmed here; I'd recommend visiting if you are in the area.

Technical Specs: Canon 1Ds3, 100-400.
