Mauna Kea Panorama

I have so many photos sitting on the hard drive, projects and ideas that remain un-realized. But every now and then I get around to completing one of those ideas and putting together something worth the effort. A couple winters ago I had an opportunity to shoot an entire 360° panorama from the top of Keck 2. I had set the camera on top of a toolbox and took photos steadily as the dome was moved through one complete rotation. A couple other photos were also taken that I could stitch into the result. The whole project made possible with the panorama features of Photoshop CS5. Twenty images were used to make the pano, resulting in a 105Mb image 26,000 pixels wide. The image shown here is downsized slightly…

It was a great day, on top of the dome after a heavy snowfall, simply stunningly beautiful. Hard work as well, shoveling snow and chipping ice off the dome at nearly fourteen thousand feet. The fellows in the image are Bill Bates (top) and Mike Dahler (below), some of the great guys who keep Keck on-sky. Bill has since retired and is sorely missed on the summit.

Postcard from the Summit – IR IRTF

A somewhat different picture of the NASA Infrared Telescope Facility. Appropriately enough this image of an IR telescope was taken with an IR camera by Mark Devenot, a fellow engineer and photographer in the Keck Operations Department.

Since this is a thermal infrared image, the colors map directly to temperature. In this image the warm asphalt of the road glows bright yellow and the cold patches of snow a cool aqua. Note how well the telescope building and dome are designed, emitting very little infrared, a good feature for an infrared telescope.

The IR camera in question is fairly low resolution, a mere 256×256 pixels, fairly typical in handheld IR cameras. Mark found a way to make an impressive image even with the low pixel count by using some of the artistic filters in Photoshop to process the image. I saw the image and had to share it with my DarkerView readers…
