DCT Status, April 22, 2013
We obtained first light images with Lowell's Discovery Channel Telescope in mid-2012, in time for unveiling at our First Light Gala on July 21, 2012. Over 700 people attended the celebration, which featured a keynote address by Neil Armstrong, making what would be his last public appearance. We were honored by his presence at this turning point in Lowell's history. See our First Light Gala page for photographs and desktop versions of the first light images.
The Large Monolithic Imager (LMI), funded by a grant from the National Science Foundation, is the DCT's workhorse instrument, featuring a 36 megapixel CCD with a field of view of nearly 13 arc minutes. It is mounted on the back of the instrument cube, at the straight-through position, with other instruments soon to be arrayed around the side ports. Lowell astronomer and instrument Principal Investigator Philip Massey has assembled gallery of commissioning images for you to enjoy and download. These demonstrate the outstanding optical quality of the telescope and apart from the color-compositing, they are completely unretouched.
With the commissioning phase of the DCT project now proceeding rapidly, we have begun to offer the first science observing nights to Lowell staff and to astronomers from our partner institutions (Boston University, the University of Maryland, and the University of Toledo). Although most nights are still dedicated to commissioning and engineering, we used the DCT on about 10 nights in Q1 2013 and are on track for aboout 15 nights in Q2 and 20 in Q3 for science observing. It is exciting to see our newest eye on the heavens doing so well what it was built to do, and we have obtained image quality as good as 0.6 seconds of arc. Stay tuned as the exciting results begin to accumulate!
Initial testing of the primary mirror supports was executed at Pulliam Airport in Flagstaff, AZ
The anatomy of the Discovery Channel Telescope: The RC instrument cube
The DCT’s Ritchey-Chretien (RC) focus will accommodate the instrument cube, which houses a suite of instruments that astronomers can use to investigate diverse aspects of our universe. Attached to the back of the primary mirror cell, the RC cube will initially contain three instruments:
The Ritchey-Chretien cube
Astronomers will use these instruments in concert to obtain a great deal of information about observed celestial objects.
