La Silla also hosts several national and project telescopes not operated by ESO. Among them are the Swiss Euler Telescope, the Danish National Telescope and the REM, TRAPPIST and TAROT telescopes.<ref name="National and Project Telescopes">{{cite web |url=http://www.eso.org/sci/facilities/lasilla/telescopes/national.html |title=National and Project Telescopes |access-date=2011-04-29 |archive-date=2020-05-31 |archive-url=https://web.archive.org/web/20200531155900/https://www.eso.org/sci/facilities/lasilla/telescopes/national.html |url-status=live }}</ref>
* The [[Euler Telescope]] is a 1.2-metre telescope built and operated by the [[Geneva Observatory]] in Switzerland. It is used to conduct high-precision radial velocity measurements primarily used in the search for large extrasolar planets in the southern celestial hemisphere. Its first discovery was a planet orbiting [[Gliese 86]].<ref>{{cite news|date=24 November 1998|url=http://www.eso.org/public/news/eso9855/|title=Extrasolar Planet in Double Star System Discovered from La Silla|publisher=ESO|access-date=2011-04-29|archive-date=2020-05-21|archive-url=https://web.archive.org/web/20200521205711/https://www.eso.org/public/news/eso9855/|url-status=live}}</ref> Other observing programmes focus on [[variable star]]s, [[asteroseismology]], gamma-ray bursts, monitoring [[Active galactic nucleus|active galactic nuclei]] (AGN) and [[gravitational lens]]es.<ref>{{cite web|url=http://obswww.unige.ch/exoplanets/coralie.html|title=Southern Sky extrasolar Planet search Programme|access-date=2011-10-05|archive-date=2011-09-27|archive-url=https://web.archive.org/web/20110927021703/http://obswww.unige.ch/exoplanets/coralie.html|url-status=dead}}</ref>
* The 1.54-metre ''Danish National Telescope'' was built by [[Sir Howard Grubb, Parsons and Co|Grubb-Parsons]] and has been in use at La Silla since 1979. The telescope has an [[Off-axis optical system|off-axis]] mount, and the optics are a Ritchey-Chrétien design. Because of the telescope's mount and limited space inside the dome, it has significant pointing restrictions.<ref>{{cite book |chapter-url = http://www.eso.org/sci/facilities/lasilla/telescopes/d1p5/ |chapter = The Danish Telescope at La Silla |title = The La Silla Observatory – from the Inauguration to the Future.

* The [[Rapid Eye Mount telescope]] is a small rapid-reaction automatic telescope with a primary {{convert|60|cm|in|adj=on}} mirror. The telescope, in an [[altazimuth mount]], began operation in October 2002. The primary purpose of the telescope is to follow the afterglow of the GRBs detected by the [[Swift Gamma-Ray Burst Mission]] satellite.<ref name="National and Project Telescopes"/><ref>{{cite web |url=http://www.rem.inaf.it/ |title=Rapid Eye Mount |access-date=2011-04-29 |archive-date=2020-05-20 |archive-url=https://web.archive.org/web/20200520114506/http://www.rem.inaf.it/ |url-status=live }}</ref>
* The Belgian [[TRAPPIST]] is a joint venture between the [[University of Liège]] and Geneva Observatory. The 0.60-metre telescope is specialised in [[comets]], exoplanets, and was one of the few telescopes that observed a [[stellar occultation]] of the dwarf planet [[Eris (dwarf planet)|Eris]], revealing that it may be smaller than [[Pluto]].<ref name=beatty>Newscientist.com, [https://www.newscientist.com/article/dn19697-former-tenth-planet-may-be-smaller-than-pluto.html Kelly Beatty – Former 'tenth planet' may be smaller than Pluto] {{Webarchive|url=https://web.archive.org/web/20120223213839/http://www.newscientist.com/article/dn19697-former-tenth-planet-may-be-smaller-than-pluto.html |date=2012-02-23 }}, November 2010</ref>
* The ''Quick-action telescope for transient objects'', [[TAROT-South robotic observatory|TAROT]], is a very fast-moving optical robotic telescope able to observe a gamma-ray burst from its beginning. Satellites detecting GRBs send signals to TAROT, which can provide a [[Minute of arc#Astronomy|sub-arc second]] position to the astronomical community. Data from the TAROT telescope is also useful in studying the evolution of GRBs, the physics of a [[Meteoroid#Fireball|fireball]] and its surrounding material.<ref>{{cite web |url=http://tarot.obs-hp.fr/tarot/ |title=TAROT website |access-date=2011-05-04 |url-status=dead |archive-url=https://web.archive.org/web/20110830125651/http://tarot.obs-hp.fr/tarot/ |archive-date=2011-08-30 }}</ref> It is operated from the [[Haute-Provence Observatory]] in France.
