With a program that does so much,
it is difficult to show enough without showing too much. We had to keep
the downloads short enough even with a phone modem. We decided to show
three different events. These are: zooming in on Jupiter and its
satellites; zooming in a group of galaxies in Virgo; and, showing the
Big Dipper at three times in history. |
The images on the screen look much better because we have reduced an entire monitor screen down to about 1/6 of its original size. This was done here to save download time.

Zoom in on Jupiter(Click the link below for higher resolution
photos)
|
|||||||||||||||||||||||||||||||||||||||
Zoom to 20º around Jupiter includes Neptune,
stars, and deep-sky. |
Zoom three steps and Jupiter, a few stars, and
many moons are visible. |
||||||||||||||||||||||||||||||||||||||||
Zoom three steps to 15' and Jupiter its nearby
moons are shown. |
Zoom two steps to 4' and we see Io is in transit
on Jupiter. |
||||||||||||||||||||||||||||||||||||||||
Zoom three steps to 15" and Io shows clearly on
Jupiter. |
Zoom two steps to 4", and we now center on Io
instead of Jupiter. |
||||||||||||||||||||||||||||||||||||||||
Zoom three steps to 1" and a map of Io is shown. |

Zoom in on Region Around M-88(Click the link below for higher resolution
photos)
|
|||||||||||||||||||||||||||||||||||||||||
Let us start at zoom Level 3
(45º). Messier objects were turned on to show the members in Virgo |
Zoom two steps to 10º. A lot of
NGC objects
now are shown around M88.M88 itself is almost lost by so many galaxies in this Virgo cluster |
||||||||||||||||||||||||||||||||||||||||
Zoom one more level to 5º and some
more
fainterNGC and IC galaxies are now visible around M88. |
Zoom two steps to 1º and M88 has a
little
more room. Note thatLEDA 169474 a faint galaxy in the PGC/LEDA catalog is near M88. |
||||||||||||||||||||||||||||||||||||||||
Zoom two more levels to 15' and we see
that LEDA
169501 is theclosest galaxy in the catalogs to M88. In the upper right note that asteroid 27857 is in the field. |
I forgot to mention that you may also
turn on the photos of mostof the galaxies. Photos of all the Messier, NGC, IC, and many others are included. These are from the DSS (Digital Sky Survey) |
||||||||||||||||||||||||||||||||||||||||
| There are a large
number of objects in the catalogs. By default they are displayed
depending on the zoom level. The more you zoom, the fainter the objects
that are displayed. You may modify to either turn a catalog on all the
tine (as we did with the Messier objects in the above example) or to
change how bright they must be to appear.
If you wish to zoom in on an object, a left click centers it. You may then zoom in using the keyboard or mouse. In regions were there are lots of objects displayed, you may right click to go through those adjacent objects to find the one you want. A right click also beings up the "More Info" button. This brings up all the data available about the object you right clicked on. These data are displayed from a number of catalogs on the CD. The data included would list the magnitude from several sources as well as size and visual descriptions. Distances between objects may be easily estimated. If you right click on the center of an object and drag the cursor to another object, the distance between the objects in minutes and seconds of arc are shown. |

The Big Dipper Over Time(Click the link below for higher resolution
photos)
|
|||||||||||||||||||||||||||||||||||||||||
Here is what Ursa Major (The Big
Dipper) looks
like today. |
If we go back a million years, it did
not look
like a dipper then. |
||||||||||||||||||||||||||||||||||||||||
Or forward a million years, it will not
look like
a dipper then either.And what is the moon doing in Ursa Major???? The ecliptic is shown there. (But remember planetary positions are only accurate for about 10,000 years.) |

| You may set the
animation to show a large number of events and how the objects move.
Setting the time to 1 million BC and time rate to 2500 years per
second, makes even the stars move. This animation may be saved to an
.AVI file. You also may step through the time changes one step at a
time.
There are a lot of interesting events you may watch. You may set your location to one of Jupiter's moons, and watch your moon orbit Jupiter and see the other moons run through the fields. Watching Saturn's rings move over the years is very beautiful. Possibly the most frequent use of this program is to see "What is Up Tonight." You may set the time to later tonight and see where the objects you are interested in are located. Watch the stars move as the Earth turns during the night. See the phase of the moon and what craters on the moon are well placed tonight. How are Saturn's moons moving tonight? While Jupiter's moons movements around the planet are easily available, what about Saturn's moons movements. Now the that rings of Saturn are almost closed, these transits and other events are visible. If you take photos of deep-sky objects, what galaxies and clusters are well placed? If there is a faint galaxy visible in your photo of a brighter one, what one is it? |
