L’obtention du le T\u00e9lescope BC600 aura \u00e9t\u00e9 une longue aventure.<\/p>\n\n\n\n

Un peu d’histoire<\/span> :<\/strong><\/h2>\n\n\n\n

<\/p>\n\n\n\n

Le 25 mars 2011, dix montreurs d\u2019\u00e9toiles de REPERES accueillent plus de 120 personnes sur le stade de Saint-Sulpice, o\u00f9 tous les lampadaires avaient \u00e9t\u00e9 \u00e9teints, sous le plan\u00e9tarium pour trois s\u00e9ances ainsi qu’une \u2018\u2018balade \u00e0 ciel ouvert\u2019\u2019 en vid\u00e9o.<\/p>\n\n\n\n

C’est donc \u00e0 cette occasion que nous faisons la connaissance de Bernard Christophe, l\u2019astronome local. Il a construit au village, dans sa maison, il y a plus de 20 ans, un imposant t\u00e9lescope, le T600. Equip\u00e9 d’un miroir de 600 millim\u00e8tres de diam\u00e8tre et 3450 millim\u00e8tres de focale sur une monture anglaise \u00e0 berceau, dot\u00e9 d\u2019une focalisation \u00e9lectrique et d\u2019un syst\u00e8me Goto. La magnitude limite pour une \u00e9toile est de 21 !<\/p>\n\n\n\n

Cet instrument a, \u00e0 ce jour, d\u00e9couvert plus de 200 ast\u00e9ro\u00efdes\u2026<\/p>\n\n\n\n

Ensuite, Bernard Christophe nous envoie le 7 juin 2015, un mail qui nous propose d\u2019accueillir son instrument dans nos locaux. Nous lui rendons rapidement visite pour savoir si nous saurions ma\u00eetriser ce tr\u00e8s bel instrument et pour voir la faisabilit\u00e9 d\u2019une transplantation aussi imposante.<\/p>\n\n\n\n

Tous les membres de REPERES pr\u00e9sents sont unanimes : Il faut relever le d\u00e9fi ! Le Conseil d\u2019Administration et l\u2019Assembl\u00e9e G\u00e9n\u00e9rale donnent \u00e9galement un avis favorable.<\/p>\n\n\n\n

D\u00e9m\u00e9nagement du BC600<\/span><\/strong> :<\/h2>\n\n\n\n

D\u00e8s le mois d\u2019ao\u00fbt 2015, les travaux commencent afin de faire la transplantation durant les cong\u00e9s du 11 novembre. Choix du lieu d’implantation, r\u00e9alisation de 3 plots de fondation (60cm de diam\u00e8tre sur 1m de profondeur) sans oublier de se caler sur la m\u00e9ridienne !<\/p>\n\n\n\n

Le jeudi 12 novembre en fin de journ\u00e9e le berceau est finalement remont\u00e9 sur sa base et pivote librement.
Tout \u00e0 droite le concepteur et donateur du T600, Mr Bernard Christophe.<\/figcaption><\/figure>\n<\/div>\n\n\n

Durant l\u2019hiver 2015-2016, nous avan\u00e7ons les travaux de nettoyage et d\u2019am\u00e9nagement et le T600 patiente sous son ancienne b\u00e2che. C\u2019est aussi le moment de mettre au point la seconde phase de l\u2019installation : conception de l\u2019abri et des armatures.<\/p>\n\n\n\n

D\u00e8s le d\u00e9but Mars, nous construisons l\u2019environnement du T600 ainsi que son abri. Encore une fois, nous profitons d\u2019un long week-end, celui de l\u2019ascension pour mettre en place le taud fabriqu\u00e9 par Denis Bache de Soissons.<\/p>\n\n\n\n

L\u2019instrument \u00e9tant enfin \u00e0 l\u2019abri, nous pouvions remonter le t\u00e9lescope, et effectuer tous les r\u00e9glages.<\/p>\n\n\n\n

Nous avons ensuite d\u00e9cid\u00e9 de renommer ce T600 (T\u00e9lescope de 600mm de diam\u00e8tre) en BC600, pour Bernard Christophe son g\u00e9n\u00e9reux donateur qui a permis \u00e0 notre Association de poss\u00e9der ce superbe instrument qui est un des plus grand t\u00e9lescope priv\u00e9 de France.<\/p>\n\n\n\n
