The Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) is designed to document the first third of galactic evolution, over approximate redshift (z) range 8--1.5.

The DEIMOS spectrograph is a multi-object being built for Keck II. was delivered in February 2002, became operational May, and now about three-quarters of the way through its commissioning period. This paper describes major problems encountered completing spectrograph, with particular emphasis on optical quality image motion. strategies developed to deal these are described. Overall, going well, it appears that will meet all performance goals.
