I was setting up a new Android tablet last night and while downloading DSS images, I was limited to 2000. It's really nice to be out in the field and go to view the DSS image without an internet connection, especially given some of the remote sites I observe at. Second, it loads so much faster when it has been downloaded. From my location, there are about 6000 NGC objects that rise above 25 degrees altitude; ideally I'd download the DSS image for all of those and just have it. Space isn't really an issue on this tablet, as it's mostly dedicated for astro uses. Maybe a new feature for SS7. Thanks!
