daily Ceres picture from the survey orbit
http://dawn.jpl.nasa.gov/multimedia/images...tml?id=PIA19572 I started a new topic, as we are no longer in the first orbit phase |

What's nice about the new view is that it appears to be a shorter exposure than PIA19568 (but with similar resolution). So in much of the area that was overexposed we can now see detail. Here's a direct comparison with PIA19568:
(All I've done is both frames 2x oversampled and PIA19568 rotated to match PIA19579. Some relative geometrical distortion between the two frames remains.) The "fuzziness" around the two brightest spots on the right side is clearly real (rather than psf), since much smaller details are resolved elsewhere in the frame. The main bright spot is still overexposed in the centre (at least on the public tifs). It seems to me that we'd need considerably better resolution to understand what's going on here... |
