What about normal cell phones

What About Normal Cell Phones?

  • Usually come w/ smaller screens (e.g. 160x128). Recently 320x200 is common.

  • MVO is a web-app for these small screens.

  • Emphasis on basic query, no data access allowed

  • Resolver mode output pretty basic.

  • Just enough to point a telescope if you’re in a field with your telescope but no internet connection.

  • Registry search prints ShortName owing to small screen size

  • Each item is a link that clicks thru to the full Registry record.

  • Registry records prints essential fields.

  • Enough information to know what the resource is, but we restrict printing (e.g. long descriptions) to minimize data transfer.
