Yes, There's a Telescope in Cardiff: The John Couch Adams Telescope at Cardiff University

Cardiff hosts a professional research telescope atop the Cardiff University School of Physics and Astronomy (Queen's Buildings, The Parade, CF24 3AA).

🔭 The Instrument

• Name: John Couch Adams Telescope (JCAT)
• Type: 24-inch (61 cm) Cassegrain reflector
• Mount: Equatorial, computer-controlled
• Housing: Roll-off roof observatory (not dome) on building roof
• First light: 2000s (refurbished historic instrument)

👨‍🔬 Namesake: John Couch Adams (1819–1892)

• Cornish mathematician/astronomer.
• Co-predicted Neptune's existence (1845–46) via orbital perturbations of Uranus — simultaneously with Le Verrier (France).
• Adams' work was theoretical; Le Verrier directed Galle to observe. Credit shared historically.
• Later: Lowndean Professor at Cambridge; Fellow of Royal Society; declined knighthood.

🔬 Current Use

• Undergraduate teaching: Astrophysics lab modules (photometry, spectroscopy, astrometry).
• Research projects: Variable stars, exoplanet transits, asteroid tracking — student-led.
• Outreach: Public observing nights (weather-permitting), school visits, National Astronomy Week events.
• Limitations: Urban site (Bortle 7–8), light pollution restricts faint-object work. No adaptive optics.

📍 Other Cardiff Astronomy Assets

• Cardiff University Observatory (historical): Original 1900s refractor — now display piece.
• Techniquest (Cardiff Bay): Science discovery center — planetarium, shows, no research telescope.
• Amateur societies: Cardiff Astronomical Society (meets at University), Barry Astronomical Society (darker site, 10 mi SW).

🎓 For Visitors

Public access is event-only (not drop-in). Check Cardiff University Physics & Astronomy outreach page or Cardiff Astronomical Society for open nights. Bring warm clothes—roof is exposed.
