Comments: The results of 73mins of imaging in pretty good conditions, worth a go at making a map! There's a clear bright spot in the Northern Hemisphere (105/+22deg) that rotated off during the session. The equatorial region is darker, and the south polar region may be brighter. There's patchy brightness in the southern 'subtropics' at 125-165/-40deg, and possibly a fainter equatorial spot near 148/-5deg, pretty hard to be at all confident of that, even with the large combination of 73min derotated data.
