Q&A: Chandra Mission

Q:
I would like to know more about chandra exposure times versus visible light images taken with Hubble for Cas A.

A:
Chandra exposure for Cas A: 3000 sec (out of 5000 sec total observing time, due to technical difficulties during this checkout phase) Optical exposure: 2400 sec. (A ground based observation. The Hubble observation didn't turn out to well, because of the wide field of view and the rapid motions)
