Kitt Peak National Observatory Star-trail

Took several hundreds pictures for KPNO star-trails with a bunch of telescopes. Every telescopes in this pictures are included in KPNO and used for solving the scientific topic. One of them, the most closed one, show telescope in dome. (Maybe u should extend the picture to see telescope clearly)

I took this picture from viewing walks of Mayall 4m telescope during my observation.
