This is a scheduled technical service with the goal to change all four Coudé prisms in the optical path. The components exhibit damages on their surfaces due to optical abrasion. By replacing the prisms we hope to significantly increase the transmission of the telescope optics, which will allow us to resume regular two-color operation and perform better on HEO missions. In order to access the optics it is inevitable to lift the entire telescope structure, so we will have to remeasure the eccentricity w.r.t. SRP and increase the occupation number in the site log after the maintenance. We hope to be back in operation in three weeks from now - please keep fingers crossed ;-) Best regards, Bernie ------------------------------------------------------ Dr. Bernd Sierk German Federal Office of Cartography and Geodesy (BKG) Observatorio TIGO (www.tigo.cl) Universidad de Concepción Concepción, Chile email: bernd.sierk@bkg.bund.de Tel: +56-41-2207035 Fax: +56-41-2207031 ------------------------------------------------------ From: Bernd Sierk ******************************************************************************** |
