The high-surface-brightness inner disk of NGC 1068 has been observed with the IUE to determine the ultraviolet spectrum and surface brightness profile. This disk is explained by an intense starburst, requiring formation of 1-2 massive stars/yr, so it is a good prototype for seeking at early epochs in the universe. Calculations of isophotal diameter as a function of redshift are presented. It is found that this disk could be resolved to z of about 0.3 from the ground or to z of about 2.0 with the Hubble Space Telescope. For z greater than about 1.3, such a disk is more easily observable than a large, normal galaxy.
