SES first light

2x2 binned ThAr spectrum using a 100um fiber.


First calibration light of the Stella echelle spectrograph on Tenerife

The STELLA echelle spectrograph has seen first calibration light on June 28, 2005. The calibration light was fed through a 200um fiber to the aquisition and guiding (AG) unit. From there, the light passed through the currently installed 100um testfiber to the spectrograph.

First star light is planned for mid-August 2005, when testing of the AG-unit is finished.
