Below are the 8 telescopes currently operating at the observatory.
The 1.52 m (60 in) Steward Observatory Telescope is aCassegrain reflector used for theMount Lemmon Survey (MLS), which is part of theCatalina Sky Survey (CSS).[4] It was built in the late 1960s and first installed atCatalina Station onMount Bigelow, which is nearby in the Santa Catalina Mountains.[1] It was moved to Mt. Lemmon in 1972, and then re-housed in its current location in 1975.[5] Its original metalprimary mirror performed poorly and was replaced in 1977 with a glass mirror made ofCer-Vit.[6] It is one of the telescopes used by students atAstronomy Camp.[7] It discovered2011 AG5, an asteroid which achieved 1 on theTorino Scale.[8]
The 1.52 m (60 in) UMN-MLOF (University of Minnesota Mount Lemmon Observing Facility) telescope began operating in 1970. It is aDall-Kirkham optical/near infrared and is of the same general design as the 1.5 m Steward telescope and another atSan Pedro Mártir.[1] The original metal mirror performed poorly and was replaced with a Cer-Vit mirror in 1974.[9] TheUniversity of California, San Diego (UCSD) was originally a partner of UMN in operating the telescope.[10]
The 1.02 m (40 in) CSS (Catalina Sky Survey) reflecting telescope is an unusual Pressman-Camichel design and is used to provide automated follow up observations of newly discoverednear-Earth objects.[3][11] It was originally located at Catalina Station and was moved to MLO in 1975.[5] It was refurbished in 2008 and placed in a new dome in 2009 before being integrated into CSS operations.[12]

The 0.81 m (32 in) Schulman Telescope is aRitchey-Chrétien reflector built byRC Optical Systems and installed in September 2010.[14][15] It is operated by the Mount Lemmon SkyCenter and is Arizona's Largest dedicatedpublic observatory.[14] The Schulman Telescope was designed from inception for remote control over the internet by amateur and professional astrophotographers worldwide, and is currently the world's largest telescope dedicated for this purpose.
A 0.7 m (28 in) reflecting telescope installed in 1963 at Catalina Station was moved to MLO in 1972.[1]
The University of Louisville Manner Telescope, a 0.6 m (24 in)Ritchey-Chrétien reflector built byRC Optical Systems, remotely operated for high precision photometry including exoplanet candidate confirmation and characterization for NASA TESS.
The 0.5 m (20 in) John Jamieson Telescope was donated to UA in 1999 and dedicated in 2005.[18] It is optimized fornear infrared observing and is operated by the Mount Lemmon SkyCenter.
