La gen\u00e8se du projet<\/strong><\/h2>\n\n\n
\n
\"\"<\/figure>\n<\/div>\n\n\n

Mr Pierre Fayadat \u00e9tait un artisan menuisier local passionn\u00e9 d\u2019astronomie. Son projet ne consistait pas simplement \u00e0 acheter un instrument d\u2019observation, mais \u00e0 construire progressivement un v\u00e9ritable observatoire priv\u00e9.<\/p>\n\n\n\n

La r\u00e9alisation s\u2019est \u00e9tendue sur vingt-huit ans :<\/p>\n\n\n\n

1959<\/strong> : d\u00e9but du polissage du miroir principal .<\/p>\n\n\n\n

1959-1987<\/strong> : fabrication progressive des diff\u00e9rents \u00e9l\u00e9ments de l\u2019instrument et du b\u00e2timent .<\/p>\n\n\n\n

1987<\/strong> : premi\u00e8re observation r\u00e9alis\u00e9e depuis l\u2019observatoire.<\/p>\n\n\n\n

Cette dur\u00e9e illustre l\u2019ampleur du travail accompli. Pierre Fayadat a d\u00fb ma\u00eetriser des techniques relevant \u00e0 la fois de la m\u00e9canique, de l\u2019optique, de la menuiserie et de la construction. L\u2019observatoire est donc \u00e0 la fois un lieu consacr\u00e9 \u00e0 l\u2019astronomie et une \u0153uvre artisanale personnelle.<\/p>\n\n\n\n

<\/a>Un instrument enti\u00e8rement artisanal<\/h3>\n\n\n\n

Le b\u00e2timent est d\u00e9crit comme une petite construction blanche surmont\u00e9e d\u2019une coupole. Il abrite un t\u00e9lescope dont le miroir mesure 310 millim\u00e8tres<\/strong> de diam\u00e8tre.<\/p>\n\n\n\n

La particularit\u00e9 essentielle du site r\u00e9side dans son caract\u00e8re int\u00e9gralement con\u00e7u et fabriqu\u00e9 par son fondateur. Le t\u00e9lescope n\u2019est pas un simple instrument commercial install\u00e9 dans une structure existante : il s\u2019inscrit dans un ensemble pens\u00e9 comme un v\u00e9ritable observatoire astronomique.<\/p>\n\n\n\n

\u00c0 l\u2019\u00e9chelle d\u2019une ville comme Joigny et de la Bourgogne, une r\u00e9alisation amateur de cette ampleur est exceptionnelle. Le site est ainsi pr\u00e9sent\u00e9 comme l\u2019un des observatoires amateurs les plus rares de la r\u00e9gion.<\/p>\n\n\n\n

<\/a> Un observatoire priv\u00e9 devenu patrimoine local<\/h3>\n\n\n\n

Pendant longtemps, l\u2019observatoire est rest\u00e9 relativement discret et peu connu du grand public. Il n\u2019en poss\u00e8de pas moins une valeur patrimoniale particuli\u00e8re, pour plusieurs raisons :<\/p>\n\n\n\n

Il t\u00e9moigne de l\u2019essor de la pratique astronomique amateur au XX\u1d49 si\u00e8cle.<\/p>\n\n\n\n

Il conserve un instrument construit selon des m\u00e9thodes artisanales et personnelles.<\/p>\n\n\n\n

Il illustre l\u2019engagement d\u2019un particulier dans une entreprise scientifique de longue dur\u00e9e.<\/p>\n\n\n\n

Il associe patrimoine technique, patrimoine architectural et histoire locale.<\/p>\n\n\n\n

Son int\u00e9r\u00eat ne tient donc pas seulement \u00e0 la possibilit\u00e9 d\u2019observer les astres. Le site raconte aussi l\u2019histoire d\u2019un homme qui a consacr\u00e9 pr\u00e8s de trois d\u00e9cennies \u00e0 donner une forme concr\u00e8te \u00e0 sa passion.<\/p>\n\n\n\n
