Milky Way Over Kitt Peak

Omega

Image Credit: Dean Ketelsen

This image was taken on the night of August 11/12. Dean Ketelsen and his wife went up a night early to see some Perseid meteors before the shower peak the next night (taking advantage of clear skies when you can during monsoon season is a must!). This shot was taken from the public parking lot with a Nikon 16mm Fisheye lens at F/2.8 on a Canon XSi camera. The shot was taken using a Polarie tracking mount running at half speed to split the trailing between the stars and trees and domes. The crescent moon was just above the horizon lighting up the 2.1 meter dome at left and the WIYN 0.9 meter telescope at right. The center of the Milky Way galaxy is centered between the constellations of Sagittarius just left, and Scorpius to the right. Vist Dean's blog at http://www.theketelsens.blogspot.com

A Windy, Starry Night

Omega

Image Credit: Dean Ketelsen

Over the last couple of observing seasons Dean Ketelsen has been working on a time lapse of the great globular cluster Omega Centauri rising over the 2.1 meter telescope on Kitt Peak. The result is shown here. These images were taken with an 85mm fast Nikon lens during a bright moon phase, where an F/1.8 lens speed made 15 second exposures possible (taken every 20 seconds). As a bonus, besides the cluster, which clears our southern horizon by only about 10 degrees, the bright galaxy Centaurus A (NGC 5128) is visible a few degrees above it. In addition, another sizable galaxy to the west, NGC 4945, can be seen as well. These objects are pointed out in the annotated picture.

High-resolution Imaging at the McMath-Pierce East

sun

High-resolution images have been taken at the National Solar Observatory McMath-Pierce East Auxiliary telescope using the new facility pco2000 2048 x 2048 CCD camera. The system has the capability of roughly 20 full frames per second, or a faster cadence with smaller frames. The camera and reimaging bench has been used for rapid imaging during the partial eclipse of May 20, 2012, and for imaging polarimetry during the Venus transit of June 6, 2012; the science data for both events is currently being analyzed.

The system is available for imaging of solar structures and has captured some solar data during good seeing. A set of images was taken during the morning of August 27, 2012, and reconstructed using the well known MOMFBD code. About 20 sub-images of 1500 x 1500 pixels with 2 milli-second exposure times and a broadband filter at 450 nm were used to reconstruct the image shown above, which reaches a resolution of about 0.2 arcseconds, matching the pixel spatial size on the imaging bench. We are investigating reimaging to use smaller pixel scales.

The small sunspots associated with NOAA active region 1554 can be seen in the image, with small penumbral filaments and umbral dots. In the rest of the image a variety of solar granulation is seen, with regions of distorted granulation visible near the sunspots marking the likely location of other magnetic fields. Some residual image blurring and distortion can be seen in parts of the 250 x 250 arsecond field of view. The system is available for imaging and imaging polarimetric experiments; contact Matt Penn (mpenn_at_noao.edu) for details.

Dr. K. Michael Merrill

Remembering Dr. K. Michael Merrill

At a time when the Observatory is already under a lot of stress and uncertainty, we have  lost one of our sages with his quiet wisdom. Many of us worked with Mike for several years, and appreciated his gentle guidance and unobtrusive style, yet he was always available to listen and help. His creative way of thinking and a softly tactful presentation style often led others to see and accept solutions that would never have been considered or noticed otherwise. Mike was a highly respected colleague, and a good friend, with a warmth of character that made you smile inside just to think of him. His calm demeanor and sharp sense of humor kept tense situations relaxed and people found themselves at ease with him. He was much like a life coach to many people within NOAO and always demonstrated the highest ethical and moral fiber. Whether it was work or everyday issues, he would listen carefully and respond sincerely, but would often add that little touch of humor that helped the day along. 

It is hard to list all of the facets of NOAO which have benefited from Mikes’s expertise. He was a great reservoir of knowledge, experience, and wisdom about observatory operations. He was a quiet man, but happy to share his thoughts when approached.  He often taught by example that an instrument is not delivered until it is producing published science. After NOAO brought its first multi-detector IR imager, SQIID, to the telescope, as the instrument scientist, Mike saw its users choking on a glut of raw data. He broke this bottleneck by producing easy-to-use, well documented software reduction tools derived from his own profound understanding of the interactions between instrument, telescope, and sky. The first instrument to use cryocoolers that are now in near-universal use, SQIID became an instrument of great scientific productivity. As a scientist, Mike was generous about honest error while ethically firm about disseminating, not suppressing, discordant results. 

There may be dark matter and dark energy, but he was one of the bright sources here and the loss of his warmth will be ever felt.

Kitt Peak

The Cone Nebula

The Cone Nebula is part of the much larger Christmas Tree Cluster, NGC2264, in the constellation Monoceros, The Unicorn. It is an emission nebula, a region of hygrogen gas (the red color) and dust, where active star formation is occurring. The Cone suggests the appearance of a christmas tree decoration located at the top of the tree-shaped cluster. With an approximate diameter of 20 light years the Cone is located at a distance of about 3000 light years from Earth. This image was taken at Kitt Peak National Observatory in Arizona on January 18, 2012 using an SBIG STL-6303E ccd camera mounted on the Kitt Peak Visitor Center's 20-inch, f/8.1, RCOS Ritchey-Chretien telescope on a Paramount ME equatorial mount. A total of 24 exposures, 300 seconds each, were taken through four separate Astrodon filters (H-alpha, R, G, and B), binned at 2x2 resolution. Camera control/initial image acquisition/processing with Maxim DL5 Pro, and final image processing using CCD Stack and Adobe Photoshop CS2 software.

Kitt Peak

The Great Andromeda Galaxy

M31, The Great Andromeda Galaxy shown with its smaller companion galaxies M32 and M110, is our nearest neighbor galaxy at approximately 2.5 million light years. These objects were captured through the Visitor Center's Takahashi FSQ-106 refractor telescope and a SBIG ST-8300C One-Shot color CCD camera. The image is the median combination of 12, five minute exposures.

WIYN 0.9meter

Beauty of the Universe Revealed by the WIYN 0.9m Telescope

NGC3628, an edge-on spiral about 35 million light years distant, the Crescent nebula (NGC6888, a shell of gas excited by HD192163, a Wolf-Rayet star) and M82, a peculiar galaxy at a distance of about 12 million light years.

These images were taken through B, V, and hydrogen alpha filters at the WIYN 0.9m in April 2011 as part of a special Visitor Center AOP program. A few nights on the 0.9m unexpectedly became available, and Glen & Joan Saurdiff responded to this opportunity to acquire images with a research telescope using the S2KB camera. The image processing was done by Flynn Haase of the Visitor Center, telescope operation by Steve Peterson and Katy Garmany.

Mayall Construction and Dave Crawford

Construction of the Mayall 4-meter telescope David Crawford

On March 2 2011, former NOAO Astronomer David Crawford celebrates his 80th birthday. In 1963 Dave became the project director for the KPNO 158-inch telescope project. In 1967 Dave took on the same job for the CTIO 158-inch. Both of these telescopes, with their excellent wide fields of view, have played major roles in both astronomical research (e.g. studies of Dark Matter and Dark Energy) and in the development and training of generations of astronomers. A co-founder of the International Dark-Sky Association, Dave has also played a major role in preserving the quality of the night-sky world-wide. Thank you Dave, and from all of us at Kitt Peak National Observatory, here's wishing you a very happy birthday!

  Kitt Peak 50th

Celebrating 50 years!
Kitt Peak National Observatory

Kitt Peak was selected in 1958 as the site for a national observatory from a survey that included more than 150 mountain ranges across the United States. Located on lands of the Tohono O’odham Nation in the Sonoran Desert southwest of Tucson, Arizona, Kitt Peak today is home to the world’s largest collection of optical telescopes under desert skies that continue to be some of the finest in the world for astronomical observations.

We will be hosting a series of events in Tucson and on Kitt Peak throughout the anniversary, including open houses, special speakers and a special pullout section in the Arizona Daily Star. And there is more to come, so please be sure to check back with us often!

 M86-NGC4438 complex

Big Galaxy Collisions Can Stunt Star Formation

A deep new image of the Virgo cluster has revealed monumental tendrils of ionized hydrogen gas 400,000 light-years long connecting the elliptical galaxy M86 and the disturbed spiral galaxy NGC 4438. Taken with the wide-field Mosaic imager on the National Science Foundation’s Mayall 4-meter telescope at Kitt Peak National Observatory, this Hydrogen-alpha image and related spectroscopic measurements of the filament provide striking evidence of a previously unsuspected high-speed collision between the two galaxies, creating enough heat to slow down and even stop star formation in the galaxy.

WIYN One Degree Imager (ODI)
Prototype Camera

The Quad-OTA CCD camera, QUOTA, has just completed an engineering run at the WIYN telescope. An OTA is a Orthogonal Transfer CCD Array and are the new generation of orthogonal transfer CCDs (OTCCD) being developed at the WIYN observatory. OTCCDs are special purpose CCDs that, when used with the NOAO developed MONSOON controller, allow the collected charge to be moved within the array during integration. Fast imaging of one or more bright guide stars in certain parts of the array allow atmospheric and other motion compensation to be made in the form of low order tip-tilt corrections. WIYN has operated the original prototype OTCCD camera, OPTIC, for over 4 years.
