Instrument Overview
The Commissioning Camera (ComCam) will be the first instrument to collect light from the GMT.
| The Giant Magellan Telescope will see its "first light" in the late 2020's. Before it can begin its scientific mission, all technical functions will be fine-tuned and verified, ensuring accurate pointing, tracking, and focus. ComCam will provide the on-axis, seeing-limited images necessary to complete this telescope commissioning. Later, ComCam will be used to validate the Ground Layer Adaptive Optics (GLAO) performance of the GMT facility Adaptive Optics System. ComCam will also be useful as a scientific instrument for both deep, broad- and narrow-band imaging. |
