The Mayall 4-meter telescope on Kitt Peak

We had two nights to start the year on the 4-meter Mayall telescope on Kitt Peak in Arizona.  We were lucky to have 2 clear nights with some of the best sub arcsecond seeing for that telescope.  Here are two HDR combines of the same 5 images of the telescope.

The first image is a Fattal combine and displays the colors more vividly.  The 5 images used my 10mm fisheye lens at f/2.8 and ISO 3200.  The shortest exposure was 1/500 seconds and the longest 1/30 seconds with the cameras nominal exposure at 1/125 seconds.

The second image is a Mantiuk '08 combine which displays the view of the 4-meter telescope and the inside of the dome fairly close to what the human eye sees the scene.
