The following are samples of Animations that Hubble-II is able to perform, and also a demonstration of your telescope's mount being controlled by Hubble to automatically point at celestial objects that you're viewing on the displays

Each display has multiple configuration options, of which just a few examples are shown here






Telescope Control


This video clip shows an example of a body being selected on the display, and a telescope being automatically aimed at it.
The  Horizon  display is used in this example, and the object selected with a mouse click is Saturn.

The animation shows that after being selected, an "Object Identification" popup window is displayed. The "GoTo" button is then pressed, and the telescope begins to slew to Saturn.   You can see the double-ringed circle, which is always showing the telescope's currently aimed position, begin to move across the display until it is enclosing Saturn. At that point, your telescope will be aimed at Saturn.


The window in the upper left of the display is the ASCOM Telescope Simulator. You can see the current Right Ascension and Declination change as the telescope slews.
Note that this functionality requires that your telescope mount is being controlled by the ASCOM Platform, and a Registered version of Hubble-II

Telescope Control on the Horizon Display




The next video clip show the telescope being repositioned to the double-star, Regulus. This time, the Star Chart display is used to select the object and start the telescope repositioning

Wanderers - The Planets in Motion


Wanderers - Star Chart Display




This video illustrates what you will see on the  Horizon  display when running the  'Wanderers'  demonstration.

The animation shows shows the same retrograde motion of the planets as seen on the  Star Chart  example above,  but from the view an observer looking out at the Horizon from their location on Earth.

The display is being updated in  One Sidereal Day  increments,  which is why the Stars are not moving in the background from day to day.

* a Sidereal Day represents the time taken by the Earth to rotate 1 revolution relative to the stars,  rather than the typical  'day',  which is measured with respect to our Sun.  It is roughly 4 minutes shorter than a Solar Day because of the Earth moving in its orbit around our Sun

Our Solar System in Motion


This video illustrates what you will see on the  Solar System  display when running the  'Our Solar System'  demonstration. The animation shows shows the Planets and Comets orbiting the sun from a perspective above the Ecliptic Plane.
If you look carefully, you will see that the orbits of the planets are not exactly circular, but are actually slightly elliptical.


Pay special attention to the motion and position of the Earth's Moon as it revolves around the Earth. Try to visualize in your mind why we see the 27-day pattern of Moon Phases.

24 Arctic Sun


This video uses the  Zenith  display to show how the Sun doesn't set,  and remains above the horizon,  24 hours a day for locations above the Arctic Circle on the longest days of the Summer. As the animation plays, you can also see that Mercury, Venus and Jupiter do not set either, while Neptune never rises above the horizon on those days.

This animation also demonstrates how multiple windows can be viewed at once.  Here the  'Planetary Positions'  and the  'Rise & Set Times'  data screens are also running in conjunction with the  Zenith  graphical display.

The Sun's Analemma Path


This video uses the  Horizon  display to demonstrates the apparent path of our Sun during consecutive days of the year.
The animation shows the position of the Sun at high-noon,  on each day of the year.


Notice how the Sun does not simply move in a vertical path up and down over the horizon from day to day,  but rather makes a Figure-8 pattern in its movement throughout the passing of a year.

As you view the Sun's position changing,  you will also see the retrograde motion of Mercury and Venus as they circle the Sun.
You can find more information about the Earth's Analemma HERE on the Wikipedia

Polaris - The North Star


This video uses the  Horizon  display to demonstrates how all the stars appear to rotate around the North Star, Polaris.

The animation updates the display in 1 minute increments to show the stars apparent circular motion around the North Star.  Of course though,  the stars are not moving,  but rather the Earth is rotating with its axis nearly aligned with the North Star.

If you click on the 'Trails' button,  you will see how Polaris is not quite perfectly aligned to the Earth's axis of rotation.   Because of this,  It will draw a small circle around the Earth's true axis of rotation.
