<guimenuitem>Show 1st/2nd Gen DSS Image</guimenuitem>:
The Digitized Sky Survey is an incredible resource: a photographic
atlas of the entire sky.  Through the miracle of the internet, you can
download a photograph of any patch of sky.  &kstars; provides one-click
access to this database.  There are two generations of the Survey; the
second generation is not yet complete, so you may get an error when
requesting a <quote>2nd Gen DSS</quote> image.  Note that the image
files are large, and may not be very aesthetic.  If other images are
available for your object, you should try them first.

<guimenuitem>Add Link...</guimenuitem>: This allows you to add your own custom
links to the popup menu of any object.  It opens a small window in which you
enter the <abbrev>URL</abbrev> of the link, and the text you want to appear in
the popup menu.  There is also a pair of radio buttons which allow you to
specify whether the <abbrev>URL</abbrev> is an image or an <abbrev>HTML</abbrev>
document, so &kstars; knows whether to launch the web browser or the image
viewer.</para></listitem>
