Jurek Brzeski (Mechanical), Peter Gillingham (Optical, Instrument Science), Gabriella Frost (Project Management) & Scott Smedley (Software) with the Echidna instrument nearing completion (October 2004). The orange support jig allows different telescope attitudes to be simulated with the Echidna instrument. © David James.

Scott Smedley observes the Echidna instrument in its inverted position. The FPI, which carries the Spine & Sky CCD cameras, is clearly visible. The tips of several spines can also be seen. © David James.

Peter Gillingham adjusts one of the Echidna modules. Half of the 12 modules are installed. The loops of white cable (actually plastic tubing) carry the optical fibre from the guide & fiducial spines to the guide CCD camera. © David James.

[Guide]
The guide camera imaging 3 guide bundles. A red filter is used to restrict the transmitted spectra of the guide stars to > 570nm as the FMOS instrument observes in IR. © Urs Klauser.

[FPI]
The Focal Plane Imager (FPI) is used for spine position feedback. © Urs Klauser.

[FPI]
Ed Penny terminates (another!) cable in the electronics enclosure. Visible in the electronics enclosure are the cooling unit (left) & the Echidna Control Computer (right). The FPI is barely visible on the underside of the base plate. © Urs Klauser.

[Electronics]
Rolf Muller connects the FPI (on the underside of the base plate) to the recently installed electronics enclosure. The black box on the base plate (beneath the electronics enclosure) houses the guide camera & back-illumination system. © Urs Klauser.

[Echidna]
The Echidna structure will eventually hold 12 modules of spines & all of the switching electronics that control the drive signals sent to each of the spines. © Urs Klauser.

[Camera]
Urs Klauser takes a photo of the spine & sky (Watec) cameras. The 45° mirror is used to image in opposite directions. The spine camera has a 0.33x telecentric lens attached to ensure images of tilted (ie. defocussed) spines are optimally acquired. © Urs Klauser.
