The magazine was first published as a quarterly under the editorship of Harlan Stetson, director of the Perkins Observatory in Ohio.

Publishing duties were assumed jointly by the Harvard College Observatory and the Bond Astronomical Club, under the editorship of Donald H. Menzel.

Originally erected at Stinchfield Woods near Dexter, Michigan, in July 1969, the telescope was moved to its current location in 1975 through the generous financial support of McGraw-Hill Incorporated and the Sloan Foundation.
Pogson awarded the honour of naming it to William Henry Smyth, the previous owner of the telescope used for the discovery.
The telescope design incorporates many new features, including hydroformed antenna surfaces, a log-periodic feed covering the entire range of frequencies from 500 MHz to 11.2 GHz, and low-noise, wide-band amplifiers with a flat response over the entire band making it possible to amplify the sky signal directly.
After Common's death the telescope with its two 60 inch mirrors and other secondary optics was purchased from his estate and installed at the Harvard College Observatory.
He also invented the Pfund telescope, which is a method for achieving a fixed telescope focal point regardless of where the telescope line of sight is positioned, and the Pfund sky compass, which arose from Pfund's studies of the polarization of scattered light from the sky in 1944, and which greatly helped transpolar flights by allowing the determination of the Sun's direction in twilight.
Soon after World War II, the Smiths sold the camp, along with the telescope, to Garfield Weston, owner of the Canadian company, George Weston Limited.
Mensa (the table; originally "Mons Mensa" for table mountain) was named after Table Mountain in South Africa where his observatory was located; the remaining dozen were named after scientific instruments and apparatuses like the telescope, microscope, and reticule.
Eventually the telescope was moved to Deutsches Museum in München, Germany, where it can still be seen in the 21st century as an exhibit.
He also wrote in the Transaction of the International Astronomical Union in 1935 On the Instrumental Adjustment of a Zenith Telescope, in which he proposed a new method of offsetting the effect of flexure by making the middle thread of the telescope follow the meridian precisely at all zenith distances.
The telescope is owned and operated by LCOGT.
The telescope was completed in 1968 with substantial NASA assistance, and is named after Harlan James Smith, the first Texas director of McDonald Observatory.
On April 24, the astronomer David Charbonneau, who led the team that made the Hubble observations, cautioned that the telescope itself may have introduced variations that caused the theoretical model to suggest the presence of water.
Radio snapshot observations with the VLA ruled out one of these fields because it contained a bright radio source, and the final decision between the other two was made on the basis of the availability of guide stars near the field: Hubble observations normally require a pair of nearby stars on which the telescope's Fine Guidance Sensors can lock during an exposure, but given the importance of the HDF observations, the working group required a second set of back-up guide stars.
For most of its lifetime, the telescope was operated in three eight-hour shifts each day, two from the US ground station at the Goddard Space Flight Center in Maryland, and one from the ESA ground station at Villanueva de la Cañada near Madrid.
The telescope site agreement with the University of Hawaii provides observer accommodation and infrastructure in exchange for open access to international proposals and 10 per cent of the observing time for the University's own projects.
Joan Roget or Juan Roget (d. between 1617 and 1624), was a spectacle maker in Girona, Catalonia, Spain who has been cited as a possible inventor of the telescope.
The telescope operated robotically, unattended for most of the night, controlled by software by Bob Denny and Jeff Medkeff.
From 1874 to 1878, J. L. E. Dreyer worked with the telescope and began the compilation of his New General Catalogue of Nebulae and Clusters of Stars.
More components of the Mizar system were discovered with the advent of the telescope and spectroscopy; a fine, easily-split visual target, Mizar was the first telescopic binary discovered—most probably by Benedetto Castelli who in 1617 asked Galileo Galilei to observe it.
The telescope is located near the Molonglo River near Canberra, Australian Capital Territory, and was constructed by modification of the East-West arm of the former Molonglo Cross Telescope, a larger version of the Mills Cross Telescope.
The dome contains a Meade 14" Maksutov–Cassegrain telescope and SBIG (SBIG-STL1001e) imaging equipment. The telescope is used for teaching undergraduate and graduate astronomy labs by the department, as well as by the Astronomy club. The observatory's imaging capabilities have been used to monitor variable stars. On the first Friday of every month during the school year the department hosts "Astronomy Open Nights" during which a lecture is given, followed by observing if the weather permits.
In 1685, Johann Zahn illustrated a large workshop camera obscura for solar observations using the telescope and scioptic ball.
The telescope and its camera were built by the ANU as a successor to the Great Melbourne Telescope at Mount Stromlo after that telescope was burnt in the 2003 Canberra bushfires.
The telescope has a compact modified Cassegrain design with a large 0.69 m secondary mirror, which gives it a very wide field of view: its single, dedicated instrument, a 268-million pixel imaging camera, can photograph 5.7 square degrees of sky.
The telescope has 50 cm (0.5 m) aperture and was from RC Optical Systems.
Other notable discoveries made by the telescope include finding 7604 Kridsadaporn, C/2007 Q3, C/2009 R1, 2012 LZ1, (242450) 2004 QY2 and (308242) 2005 GO21.
