A streaked multiple pinhole camera technique, first used by P. Choi et al. to record time- and 2-D space-resolved soft X-ray images of plasma pinches, has been implemented on laser plasmas at NOVA. The instrument is particularly useful for time-resolved imaging of small sources (< 150 {mu}m) such as implosions for which the necessary alignment accuracy is relaxed from {le} 10 {mu}m for a single pinhole, to 200 {mu}m for a nine pinhole column. Results at 20 {mu}m, 30 ps resolution are presented for > 2.5 key imaging, complementing the existing 1--3 key streaked X-ray microscope capabilities at NOVA.
