One Billion Pixels

The last night of engineering verification I was thinking about what the full focal plane version of ODI would be like.  We now know that even in non-OT mode, the instrument can produce images better than 0.4 arcseconds over its full field.  We know how to make detectors that will work fine in  static and coherent modes.  And so I produced this image of M33.  It's a five minute exposure in the r band.  It is 63 arcminutes wide by 65 arcminutes high.  The corner chips have been used for guiding, allowing us to remove telescope shake and some fraction of the ground layer seeing.  The screenshot doesn't do it justice.  Even the 30-inch display doesn't do it justice.
