Adding Images from the Digitized Sky
Survey:
You can use Starry Night’s web
link to the Digitized Sky Survey to
download and paste in images of galaxies,
nebula, or any other object. See
“Downloading Photographic Images
” on
page 77 for more about the Digitized Sky
Survey.
To add an image using the Digitized Sky
Survey:
1 Right-click (Ctrl-click on the Mac) on
the object of which you would like to
download an image.
2 Choose Add Image from the object’s
contextual menu to open the Image
Editor. Starry Night will have
automatically guessed at the area of the
sky for which you wish to download an
image, based on the size of the original
object you selected. This area will be
marked with a yellow square. In most
cases you will not need to change this,
but you can enlarge, shrink or shift the
image bounds if you wish, using the
Image Editor controls, described in
“Image Editor Controls
” on page 174.
3 Click the From DSS button. Starry
Night will begin downloading the DSS
image. This may take a few minutes,
depending on the server load. Once the
image is downloaded, it will appear in
the Image Editor dialog box.
Tip: If you wish, you can also download
the DSS image into your Internet browser,
by pressing the Web button. If you then
copy this image to your clipboard, you can
paste it into the Image Editor by pressing
the Paste button. The Paste button can be
used to paste in any images that are on
your clipboard.
4 The image should automatically be
aligned with the background stars. If
for some reason, it is not perfectly
aligned, you can align the image using
the Image Editor controls.
5 When you are satisfied that your image
is correctly aligned, press the Details
button in the upper left corner of the
window, to add an image name, add
other information, and use the
Background Reduction box (if
necessary). Then press Save twice to
exit the Image Editor.
Note: Downloading images from the
Digitized Sky Survey is not the same as
downloading star data from the Internet
(discussed in “Adding Objects 3 (Stars)
”
on page 169). When you download star
data, each star can be selected as an
individual object in Starry Night. When
you download a DSS image, the individual
stars in this image cannot be selected, and
no information can be obtained about
them from the program.
