N. Lesparre, The installation of the telescope received advices and authorization from the Director of the National Natural Park of Guadeloupe (www.guadeloupe-parcnational.fr) On the field, the maintenance and the servicing of the telescope are ensured by Fabrice Dufour. The construction of the telescopes benefited from the expertise of Bruno Carlus (computer) Pascal Rolland (mechanical engineering), and Sylvain Vanzetto (optical fibres) Very constructive reviews were provided by H. Tanaka and an anonymous Referee. The DIAPHANE project is financially supported by the IPGP (www.ipgp.fr) BQR grant, the DOMOSCAN ANR (www.agence-nationale-recherche.fr) project, the helicopter station of the French Civil Security
