The Telescopes

The collection of telescopes at the Stull Observatory has been described as one of the best for teaching anywhere. All told, we have 7 independently housed telescopes ranging in size from 8 to 32 inches, as well as several smaller instruments used as finders and guiders

Most of the names given our telescopes reflect important connections with and contributions to our observatory.

Details of the Individual Telescopes

The Fitz 9 inch refractor

Our oldest, most historic telescope, the Fitz was purchased by Alfred University in 1863. Built by the American optician, Henry Fitz (hence its name), it is a nine inch, f/13 refractor. Originally housed in the Rogers Observatory formerly near the heart of the Alfred University campus, it was mothballed for decades and then rediscovered and put back to use in the late 1950's and early 1960's. The orginal wooden tube was badly damaged during the instrument's "lost years" and was replaced with a metal one at that time. Used for our public nights as well as our introductory labs, it remains a fine telescope for the study of planets, double stars and bright clusters.


The Hunt, Schwartz and "Baby Dome" 8 inch Schmidt-Cassegrains

These three telescopes are the only mass-produced telescopes at the Observatory. Named for Lee and Mary Hunt, the father and mother-in-law of the Observatory's modern founder, John Stull, the Hunt is a Meade 8 inch LX-200. This is a computer-controlled telescope which is used for student projects and general viewing.

The "Schwartz" is a .

The "Baby Dome" contains an 8 inch Celestron SCT and is used with a Daystar filter for H alpha monitoring of solar flares using a high-speed video technique.


The Olson 14 inch Newtonian reflector

The Olson is a 14 inch f/6 Newtonian reflector named for the late founder of the Ash Dome Company L.E. "Ole" Olson. Equipped with an ST-6 CCD imager and a 4x5 film camera, this instrument is used by beginning labs as well as the Astronomy Club. After proper training, Alfred University students can use this instrument without faculty supervision.


The Grindle 16 inch Cassegrain Reflector

The Grindle, named for Paul Grindle, the head of Harvard Apparatus (formerly Ealing Corporation) is a heavily modified Ealing "Educator" Cassegrain (16 inch, f/11 - f/3.2). It retains options for use either in Cassegrain or prime-focus mode. A 6 inch f/10 refractor as a guider makes this a particularly nice all-purpose installation.


The "Rich" Rose 6 inch Solar Heliostat

The Rose, named for .


The Metzger 20 inch Newtonian Reflector

Named for a local artist and amateur astronomer who was active in the re-establishment of the Observatory, the Metzger is a 20 inch f/5.5 Newtonian reflector. It is the largest of the telescopes regularly used by our introductory astronomy lab.


The Austin-Fellows 32 inch Newtonian Reflector

This is our largest telescope, at 32 (and 1/4 !) inches, at f/4. It is computer-controlled from a warmroom in one corner of the dome and includes an automated filter wheel and focusser as well as the option for various CCD's. It is used by upper-level students as well as faculty for more advanced projects and research. Its name recognizes both the contributions of Austin Grindle, late general manager of Harvard Instruments, and those of all Alfred University faculty and staff who have died since the re-establishment of the Observatory in 1966.
