Hartung–Boothroyd Observatory is a leading educational facility, aiding in the study of astrophysics, tracking asteroids, and fostering diverse academic collaborations.
Perched on Mount Pleasant in the town of Dryden, New York, the Hartung-Boothroyd Observatory (HBO) stands as a testament to the celestial curiosity that Cornell University has nurtured for decades. It is a gateway to the stars, a place where the heavens unfold in wondrous detail to the eyes of astrophiles and the lenses of powerful telescopes.
The observatory is home to a reflecting telescope, one of the largest in New York State dedicated to both education and research. This remarkable instrument, housed under a retractable dome, has provided students and researchers with direct experience in astronomical observations since its establishment in 1974.
HBO isn’t just an observatory; it is a bridge between the terrestrial and the cosmic. It represents an educational philosophy that values direct engagement with the subject of study. Undergraduates, graduates, and faculty members flock to the facility to engage in projects that range from studying variable stars and exoplanets to tracking asteroids. Here, theoretical astrophysics meets the tactile world, allowing for an integrated understanding of the universe’s complexities.
It is used mainly as a Cornell University (Ithaca, New York) teaching facility for upper-level astronomy classes. The observatory is named financial contributions of M. John Hartung ’08 (chemical industrialist and donor) and in honor of the labor of Samuel L. Boothroyd (founding professor and chairman of astronomy 1921–1942). The telescope construction began in the 1930s and the observatory was dedicated in 1974. It contains the James R. Houck 60 centimeter telescope and various instruments.
The James R. Houck telescope at HBO was a project initiated by its namesake in 1972, using optics and a lightweight tube which had been fabricated in the late 1930s by Samuel T. Boothroyd, Cornell’s first astronomer, and a mounting constructed by George Gull ’72 as his senior design thesis in Mechanical Engineering.
The telescope, control electronics and instruments are largely the result of work done by undergraduates since 1970. It was manufactured by the students at the Tompkins, Tioga and Seneca BOCES and by Therm, Inc., with mirror coatings by Evaporated Metal Films corporation, all in Ithaca. The latter corporation was founded by members of Boothroyd’s scientific team, as he pioneered the use of evaporated metal coatings in astronomical optics. The telescope and observatory were dedicated in 1974.
The primary mirror is made of Pyrex from the Corning Glass Works and is in fact from a 1/8-scale test pour by the Corning company in preparation for the making of the 200″ Palomar mirror. It is 0.635 m (25 inches) in size, but the outer half inch is masked. The focal length of the mirror is 2.5m (100″) or f/4.
The Cassegrain design of the James R. Houck telescope is a combination of a primary concave mirror and a secondary convex mirror, often used in optical telescopes, the main characteristic being that the optical path folds back onto itself, relative to the optical system’s primary mirror entrance aperture. This design puts the focal point at a convenient location behind the primary mirror and the convex secondary adds a telephoto effect creating a much longer focal length in a mechanically short system.
The secondary is an 8″ mirror made of Cervit (a low thermal coefficient material). In combination with the primary, it yields a final f/13.5 beam to the nominal focus, which lies 18.5″ behind the primary mirror’s vertex. At nominal focus, the plate scale is about 24 arcsec/mm, with an effective focal length of 8.57 m.

The dome itself, like all professional observatories, is unheated. The telescope and instrumentation can be controlled from a neighboring control room which is heated and offers standard amenities plus several computers for simultaneous data reduction.
The observatory was founded by James Houck and managed by him through 2006. The principal contact is Don Barry, who managed the facility from 2006-2015, and taught Experimental Astronomy using the facility.
“Graduates” of the HBO project are now senior engineers and technical managers as well as graduate students, research associates and faculty at major universities.
Moreover, the observatory is a beacon for interdisciplinary collaboration. It’s not uncommon to find astronomers working alongside computer scientists, engineers, and educators. This cross-pollination of ideas enhances the potential for innovation, fostering new techniques in data analysis, instrument design, and educational methods. The observatory’s role extends beyond its primary function; it is a hub of convergence for diverse academic disciplines, all under the umbrella of exploring the unknown.
HBO also contributes to the global astronomical community through its research. The data collected here feed into larger networks of observation and analysis, aiding in the collective endeavor of mapping and understanding the universe. Its strategic location in upstate New York, away from the light pollution of large urban centers, grants it relatively clear night skies, making it an invaluable resource for both optical astronomy and astrophotography.
In an era where space exploration has captured the public imagination like never before, observatories such as the Hartung-Boothroyd are more crucial than ever. They serve as terrestrial launchpads, propelling minds into the realm of scientific inquiry. Here, the vastness of space becomes approachable, the mechanics of the cosmos decipherable, and the mysteries of the universe a little less mysterious.
As the night falls and the stars emerge, the Hartung-Boothroyd Observatory continues its silent vigil over the heavens. It stands as a beacon of knowledge and discovery, an educational catalyst, and a gateway to the stars. For the students and astronomers who work from this dome on Mount Pleasant, HBO is more than an observatory—it is a vessel navigating the infinite ocean of the night sky, a journey that begins in the heart of Cornell University and extends to the edges of the observable universe.
The Newgrange facade and kerbstones consists of stones from various locations, believed to be transported by sea and river.
The Newgrange façade and entrance of today is a creation from the large quantity of small stones unearthed and conserved during excavation given form by a steel-reinforced concrete retention wall.
The brilliant white quartz cobblestones were collected from the Wicklow Mountains, 31 miles to the south. Our guide called them “sunstones” for the way they reflect sunlight. In the following photograph is white quartz, the same excavated 1967-1975 from the Newgrange site and incorporated into the facade, I collected from “Miners Way” along R756 (above Glendalough).
You can also see in these photographs dark rounded granodiorite cobbles from the Mourne Mountains, 31 miles to the north. Dark gabbro cobbles from the Cooley Mountains and banded siltstone from the shore at Carlingford Lough both locations on the Cooley Peninsula where my mother’s family still has farms.
The stones may have been transported to Newgrange by sea and up the River Boyne by fastening them to the underside of boats at low tide. None of the structural slabs were quarried, for they show signs of having been weathered naturally, so they must have been collected and then transported, largely uphill, to the Newgrange site. The granite basins found inside the chambers also came from the Mournes.
Geological analysis indicates that the thousands of pebbles that make up the cairn, which together would have weighed about 200,000 tons, came from the nearby river terraces of the Boyne. There is a large pond in this area that is believed to be the site quarried for the pebbles by the builders of Newgrange.
Most of the 547 slabs that make up the inner passage, chambers, and the outer kerbstones are greywacke. Some or all of them may have been brought from sites either 3 miles away or from the rocky beach at Clogherhead, County Louth, about 12 miles to the northeast.
Approaching Newgrange for the first time
Michael Joseph “Brian” O’Kelly was selected to undertake the direction of the excavation of Newgrange during a 1961 meeting of “those who had a professional interest in the monument” organized by PJ Hartnett, the archaeological officer with Bord Fáilte Eireann (Irish Tourist Board) and a former pupil of Professor O’Kelly’s. Excavation commenced in 1962 and continued every summer for a four-month season up to and including 1975.
The aim of the excavation was to discover as much as possible about the archaeological and historical context of Newgrange and the people who built it and to discover what its original finished appearance was so as to direct a reconstruction, conservation and restoration of the structure to its former condition and appearance.
The last year of excavation was 1975, Michael J. wrote “We determined in 1975 that that should be our last season of excavation at Newgrange. We had investigated approximately one third of the structure and we had discovered much about it that was new, both in its structure and in its ornament, while radiocarbon had pushed its date back by 1,000 years……”
“…We felt that the other two thirds should be left for a future excavator, who, working with new knowledge and perhaps with better methods and new scientific approaches, should have large areas untouched by us in which to test, check and re-evaluate our findings.” From The Restoration of Newgrange by Michael J.O’Kelly. Antiquity LIII, 1979.
“Between the bright sky and the long glittering silver ribbon of the Boyne the land looks black and featureless. Great flocks of starlings are flying across the sky from their nighttime roosts to their daytime feeding places. The effect is very dramatic as the direct light of the sun brightens and casts a glow of light all over the chamber. I can even see parts of the roof and a reflected light shines right back into the back of the end chamber.” The recorded words of Prof O’Kelly spoken in the tomb of Newgrange on the 21st December 1969.
Night Spring Sky, North America
Some nights I travel to the farthest reaches of the universe right from my backyard. Here is a guide to the spring night sky for those of you in the northern hemisphere. Even sunbathing we are time travelling, bathed in starlite over 8 minutes old. Time taken by sunlight to reach Earth = (150,000,000/3,00,000) seconds = 500 seconds = 8 minutes 20 seconds).
In the the long view
On this occasion we will explore a time machine found four miles south of Kells, County Meath, Ireland.
Step into this pool and you, too, can emerge 4,000-odd years later, skin intact, to achieve fame and fortune, a place in a museum and the record books if such exist 6019 AD. Reference the Cashel Man from Cúl na Móna bog near Cashel in County Laois, Ireland who now resides within the National Museum of Ireland.
True, post mortem fame is hollow for the individual. Maybe, attaching your life story engraved on a gold plaque with a gold chain encircling your torso will offset the loss of your bones (dissolved in the acidic waters) and life itself.
The water of this pool is colored dark by long decayed vegetable matter. Beware of walking the bog surface, it is dangerous and destructive to the environment. Pam and I visited Girley Bog on our tour of County Meath, Ireland.
