Android SkySafari users will find the equivalent options under the Appearance section, below. Ambient Sound: Controls the use of ambient sound in the app. Tapping the entry will display a sound picker where you can choose from several ambient sounds or none at all. You can add you own custom ambient sounds to the list. On iOS, place them in the Documents directory using iTunes file sharing. On Android, add them to the app's Sounds directory. Sound Effects: Controls the use of sound in the app.
When turned on, SkySafari plays sounds in response to events such as selecting a new object, connecting to a telescope, and so on. When turned off, SkySafari does not play sounds. Tilt to Use Compass: When turned on, you can tilt your iPhone, iPad, or Android device upward to activate the compass. Once activated this way, touch the screen anywhere to turn the compass off. Turn "Tilt to Use" off if you find that you're accidentally activating the compass too often, or if you prefer to activate it from the main toolbar.
Please Note: the compass will be turned off if you connect to a telescope, or lock on the telescope's position in the sky chart. See the Scope Control view Help page for more information. If your device does not have a compass, this option is disabled.
When the compass has been activated, the coordinate system will change to Horizon coordinates see above. You can turn them off if you want to see the sky chart without any coordinates superimposed. Chart Animations: Provides animated panning to objects that you select and center in the sky chart. Also provides smoother panning. When turned on, the chart "glides to a halt" when you remove your finger after swiping. When turned off, the chart stops moving instantly when you remove your finger.
This allows a continuous connection to a telescope. Normally this is desired but you may want to turn this OFF when using a custom keyboard that is already reddened or when using a red film over the screen. Toolbar Icon Order: Lets you rearrange the items on the main sky chart toolbar.
Tap this item to show the list of toolbar items. Tap and drag the "grip" on the right side of an item in the list to rearrange it. Tap Done when finished. It's not available in the Android version. These options let you control what happens when you rotate your device from portrait to landscape mode or vice-versa.
Allow Auto Rotation: When turned on, the main sky chart and other views automatically rotate as you turn your device from portrait to landscape mode. When turned off, all views stay in portrait mode, regardless of how you are holding your device. On the iPad, this setting overrides the hardware rotation lock.
In other words, if the auto rotation setting is turned off, all of SkySafari's views will remain in portrait mode even if the iPad's hardware rotation lock is disabled. You may want to have other iPad apps auto-rotate, but keep SkySafari in portrait orientation.
Toolbar in Landscape: When turned on, the main toolbar and status bar appear when your device is held in Landscape mode, as well as in Portrait mode. If this setting is turned off, the toolbar will disappear in Landscape mode, giving you a "full screen" sky chart view.
SkySafari can notify you about satellite events and planet risings. These notifications are generated for next 24 hour period each time SkySafari is brought to the foreground. If you go for a day or so without using SkySafari, the notifications will stop.
It will also notify you when an Iridium satellite is about to flare. Do Not Disturb: When turned on, no notifications will be delivered during the specified time period. The settings in this view let you control the display of the local horizon, and the sky background. In SkySafari Plus and Pro, note that the horizon is not visible if you are not displaying the sky chart using horizon coordinates!
Use horizon coordinates to show the horizon. When turned off, most of the other settings in this section are disabled. The horizon line itself is still visible. You can select a specific panorama from the list in the section below. Show Cardinal Points: Sets whether the cardinal points are displayed along the horizon line. Cardinal points label the north, east, south, and west directions on the horizon.
Show Daylight: When turned on, the sky color changes with the cycle of day and night. When turned off, the sky background color is always black. Show Horizon Glow: When turned on, the horizon is drawn with a soft glow that increases with daylight to simulate atmospheric haze. When turned off, the horizon is always drawn against a clear sky background.
Horizon Altitude: Lets you determine when objects rise and set above a specific altitude. Objects below the altitude you select will be considered below the horizon. You can use this to quickly identify objects which - even though technically above zero degrees altitude - are still too low in the sky to be easily observed. It's usually not worthwhile to observe objects below an altitude of 10 - 15 degrees, since they are lost in atmospheric haze.
This section lists the horizon panoramas that are available in SkySafari. The currently-selected panorama is shown with a check mark. The panorama is only displayed if you've selected Panoramic Image display option above. Choosing any item from the list of horizon panoramas will automatically select this option! You can create your own horizon panorama - for instance, an image of your own back yard, or your favorite observing site.
You can then import it into SkySafari, to show the sky as it realistically appears from your location. Resize your panorama image to dimensions of exactly pixels wide x pixels tall.
Make sure your image contains an alpha or transparency layer that accurately indicates the parts of your panorama that are opaque the ground, trees, buildings, etc. If you are using SkySafari on an iPhone, iPad, or iPod touch, you can import your horizon panorama using iTunes file sharing. Select your iOS device when it appears in iTunes, then find the "Apps" section that lists all the apps on your device.
Choose SkySafari from the list of apps. If everything works correctly, your image will then appear in the list of horizon panoramas in SkySafari. You can select and display it just like SkySafari's other built-in horizon panoramas. If your horizon panorama doesn't appear in SkySafari's list, make sure it's in PNG format, and that its name ends with ".
Make sure its dimensions are x , and that's a bit RGBA color image with an alpha transparency layer. If all else fails, you can email your image to Simulation Curriculum technical support, and we can try to debug it for you.
To do this, connect your Android device with a USB cable to a computer. Then mount your Android's SD card on your computer, so it appears as a disk. For example, if you own SkySafari Pro, copy your panorama to the following directory on your SD card:. The settings in this view control the display of planets, moons, and other "minor bodies" in the solar system asteroids and comets , as well as artificial Earth-orbiting satellites.
Show Planets: Displays planets and moons in the sky chart. Planet grids show the orientation of the planet's equator and rotational axis. Their north poles are drawn as bold lines; south poles are shown with lighter lines. Note: this option is only available in SkySafari Plus and Pro. When turned off, planets shown as fully illuminated, without any night side shading. To see these objects' surfaces unobscured by clouds, turn off this option. This option can slow performance when zoomed in a planet's disk, but generates a very pretty view.
Spacecraft that have landed on other solar system objects, and cities on Earth, are indicated with a green dot and label. Only the largest features are labelled when a planet's disk appears very small; to see more labels for smaller features, zoom in on the planet.
All of these are small, asteroid-sized objects that are only visible in large professional telescopes. Note: this option is only available in SkySafari Pro. Show Planet Orbits: Shows orbital paths of the major planets around the Sun. Since the planets orbit in the nearly the same plane as the Earth the Ecliptic plane , their orbits appear near the Ecliptic line - the Earth's orbit as seen from the Earth - in the sky. Show Moon Orbits: Shows orbital paths of the moons around their primary parent planet.
You may need to zoom in on a planet to see its moon orbits; Mercury and Venus have no moons! Selected Object Orbit: Shows the orbit of the selected planet, moon, asteroid, comet, or satellite.
You need to select such an object and turn on this option to show its orbit. Selected Object Path: Shows the apparent path of a solar system object across the sky, with its position at specific dates labelled. The solar system object must be selected, and you must be viewing it from the Earth's surface, in order to see the path.
When this option is turned on, the Earth's or Moon's umbral and penumbral shadows are shows as concentric circles. Inside the smaller umbral shadow, the Sun is totally hidden; inside the larger penumbral shadow, the Sun is only partially blocked. This can be helpful for simulating lunar and solar eclipses, and illustrating the difference between total and partial eclipses. Magnitude Limit: This item lets you set the faintest planets, moons, asteroids, comets, and spacecraft that the sky chart will display.
You can use this item to filter out the many hundreds of faint asteroids and comets that are not observable in backyard telescopes - or you may want to show them all! Planet Magnification: This slider lets you magnify the Solar System's major planets by a factor of up to 10,x their true size. The planets are very small compared to the space between them. This option is useful for showing comparative views of the planets from different perspectives.
Moon Magnification: This slider lets you magnify the moons of the planets by a factor of up to x over their true size. Since most moons are very small compared to their primary planet, this option lets you exaggerate them to make easier comparative views. SkySafari normally updates its database of asteroid, comet, and satellite orbits once per week.
In SkySafari Plus and Pro, you can tap this button to download new asteroid, comet, and satellite orbit data any time your iOS or Android device is connected to the internet. SkySafari will download the following files:. These downloads should take 10 - 30 seconds if you are connected to the internet by Wi-Fi, and a 1 - 3 minutes if you are connected by a cellular data network. If successful, SkySafari will report the number of asteroid, comet, and satellite orbits that it has updated.
If that number is zero, it probably means SkySafari can't connect to the on-line data sources for this information because the server is down, or because you are not connected to the internet, etc. Updating your orbit data every month or so is a good idea. It will ensure that SkySafari's position predictions are accurate. This is especially true for satellites, whose orbits change rapidly due to atmospheric drag, and due to perturbations from the Earth's non-spherical gravity field.
Updating also ensures that as new objects are launched - or discovered! The settings in this view let you control the display of stars, including the number of stars that will be shown, the size and color of the star symbols, and the labelling of stars with their names or catalog numbers.
Show Stars: Sets whether stars are displayed in the sky chart. When turned off, most of the other settings in this view are disabled. Magnitude Limit: Sets the star magnitude limit. This determines the faintest stars that are visible in the sky chart. The brighter a star, the lower its magnitude. The faintest stars visible to the naked eye are about magnitude 6. Very bright stars can have negative magnitudes; the brightest star in the sky, Sirius, is magnitude The magnitude limit will change automatically as you zoom the sky chart in and out.
When zoomed in, fainter stars are displayed. Proper Names: Sets whether proper names are displayed for stars when possible. When turned off, stars' names are displayed using their catalog numbers e.
Greek Symbols: Sets whether greek symbols are displayed for stars which have Bayer letters. When turned off, greek letters are spelled out in English, e. Name Density: Sets the percentage of stars whose names are displayed on the sky chart. For binary stars with known orbits, this option also displays the orbital path of the secondary component relative to the primary. Turn this option on, then zoom in on Sirius or Alpha Centauri, and take a look! Symbol Size: Sets the size of the star symbols.
Use small, subtle star symbols to give the screen the appearance of the night sky. Color Intensity: Sets the displayed intensity of the color difference between stars of different spectral types. The settings in this view let you control the display of star cluster, nebulae, and galaxies - including the selection of deep sky objects that are shown, and the labelling of objects with their names or catalog numbers.
Show Objects: Draws symbols for star clusters, nebulae, and galaxies in the sky chart. Show Images: Displays images of deep sky objects in the sky chart.
When turned on, Digitized Sky Survey images of several hundred best-known deep sky objects are drawn at their true size and orientation in the sky chart. Deep sky images can be displayed independently of deep sky object symbols above , and vice-versa. Best-Known Only: Sets whether only the best-known deep sky objects are shown in the sky chart. These objects include the Messier objects, the Caldwell objects, and any other deep sky objects with a proper or common name.
The Messier Catalog is a famous list of prominent deep sky objects compiled by the 18th century astronomer Charles Messier. The Messier catalog includes some of the most prominent star clusters, nebulae, and galaxies visible from the northern hemisphere, such as the Hercules Cluster M 13 and the Whirlpool Galaxy M It includes additional "Messier-quality" deep sky objects which Messier missed, many because they are only observable from the southern hemisphere. Together, the Messier and Caldwell lists include most of the deep sky objects easily visible in backyard telescopes from both hemispheres.
Show in Wide Fields: allows deep sky objects to be displayed when the field of view is wider than 45 degrees. This option is turned off by default, since deep sky objects can only be seen through binoculars or telescopes, which have very small fields of view. However, turning this option on may let you see the distribution of for example galaxies across wide areas of the sky.
Magnitude Limit: Sets the deep sky object magnitude limit. This determines the faintest deep sky objects that are visible in the sky chart. The brighter an object, the lower its magnitude. When zoomed in, fainter objects are displayed. Intensity: Sets the brightness used to display deep sky object symbols and names. Show Names: Sets whether deep sky objects' names are displayed next to the objects in the sky chart. Proper Names: Sets whether proper names are displayed for deep sky objects, when possible.
When turned off, deep sky objects names are always shown using catalog numbers e. Name Density: Sets the percentage of deep sky objects whose names are displayed on the sky chart. Globular Clusters: Sets whether globular clusters are displayed in the sky chart. These are dense concentrations of stars, typically containing tens of thousands to millions of stars.
These massive clusters are among the oldest objects in our galaxy. Examples are M 13 in Hercules and M 22 in Sagittarius. Bright Nebulae: Sets whether bright nebulae are displayed in the sky chart. These are glowing clouds of gas usually found in the disk of the Milky Way.
These nebulae glow either from the reflection of light from nearby stars or from the emission of light produced by nearby stars heating the nebulae. Dark Nebulae: Sets whether dark nebulae are displayed in the sky chart. These are opaque clouds of cold dust which obscure the light from the stars behind them.
They are mostly located along the Milky Way. Planetary Nebulae: Sets whether planetary nebulae are displayed in the sky chart. These are expanding shells of gas expelled from a star late in its life. A round, planet-like appearance led to the name "planetary nebulae" in the eighteenth century, though there is no actual connection with planets.
Galaxies: Sets whether galaxies are displayed in the sky chart. Galaxies are immense star systems outside of our own Milky Way galaxy; many are larger than our own. The total number of galaxies is in the billions, and they extend to the edge of the known universe. Most galaxies are classified as spiral galaxies, elliptical galaxies, or irregular galaxies, based on their appearance.
The Milky Way is the visible concentration of stars, star clusters, bright gas clouds, and dark dust lanes that lie along the plane of our galaxy in the sky. The settings in this view control how the Milky Way is displayed in the main sky chart. When turned off, the Milky Way is not drawn, and most of the other settings in this section are disabled.
The view shows the distribution of glowing ionized hydrogen gas clouds in our galaxy's star-forming regions. The colors in this image represent specific wavelengths of infrared light.
Cyan blue-green represents light emitted predominantly from stars and galaxies at a wavelength of 3. Green and red represent light mostly emitted by dust at 12 and 22 microns, respectively. Galactic dust clouds are visible at these wavelengths. Constructed from observations of the sky at wavelengths spanning microns to 1 cm GHz to 30 GHz.
The Haslam MHz map is derived from 4 separate surveys. In this 3-color image, red is 0. For comparison, the energy of visible light is between 2 and 3 electron volts. Intensity: Sets the brightness level of the Milky Way when shown as a filled area or realistic image. Fade in Small Fields: When turned on, the Milky Way's intensity will fade to zero as the field of view decreases from 10 to 1 degrees wide. It is often not useful to show the Milky Way in very small fields of view.
The settings in this view let you show or hide grids which display the major celestial coordinate systems, as well as the reference lines and points that those systems are based on.
Show Grid: Sets whether a celestial coordinate grid is displayed on the sky chart. When turned on, the following items are enabled:. Celestial Equator: Sets whether the celestial equator is displayed on the sky chart. The celestial equator is the plane of the Earth's equator projected onto the celestial sphere. Galactic Equator: Sets whether the galactic equator is displayed on the sky chart. The galactic equator is the plane of the Milky Way galaxy projected onto the celestial sphere.
Ecliptic Path: Sets whether the Ecliptic path is displayed on the sky chart. The Ecliptic is the plane of the Earth's orbit projected onto the sky.
It is also the annual path of the Sun around the celestial sphere. Meridian Line: Sets whether the meridian is displayed on the sky chart. The meridian is the projection of your longitude on Earth onto the celestial sphere. It extends from the northern horizon through the zenith to the south cardinal point on the horizon.
An object is said to transit when it crosses the meridian. Celestial Poles: Sets whether the celestial poles are displayed on the sky chart.
The celestial poles are where the Earth's polar axis i. The north and south celestial poles are currently in the constellations Ursa Minor and Octans, but they move slowly over the centuries due to precession.
Galactic Poles: Sets whether the galactic poles are displayed on the sky chart. The north and south galactic poles are where a line perpendicular to the plane of the Milky Way galaxy intersects the celestial sphere. They are currently located in the constellations Coma Berenices and Sculptor, respectively. Ecliptic Poles: Sets whether the ecliptic poles are displayed on the sky chart.
The ecliptic poles are where a line perpendicular to plane of the Ecliptic intersects the celestial sphere. The north and south ecliptic poles are in the constellations of Draco and Dorado, respectively. This marks and labels the points directly overhead and underneath your feet. Settings Files let you save all of your sky chart options so you can restore them at a later date. You can email settings files to yourself, or send them to your friends, so that you or they can easily reproduce a sky chart which you have created.
To do all of these things, select the Save and Restore Settings item from the main Settings view. Default Settings: SkySafari creates a default settings file the first time you run the app.
This settings file is called "Default Settings", and it contains a "snapshot" of the app the first time it was launched. You can restore SkySafari to its initial state at any time by choosing this settings file. To create your own settings files, tap the "Save New Settings File" button.
SkySafari will make another "snapshot" of all the app's current settings, and save them as a settings file called "Current Settings. You can edit the settings file name to something else if you want a more descriptive title. Description: SkySafari generates a default description for your settings file, to give you an idea of what's inside it.
You can edit this description as well. When you are satisfied with the name and description, tap the "Done" button in the upper right side of the status bar to return to the list of settings files that you have already saved - your new settings file is added to the list! To restore a saved settings file, tap its name in the list of settings files. SkySafari will display the file's description, to let you make sure this is the file you want.
If so, tap the "OK" button - and all of the app's settings will be replaced with those from the settings file. You can tap the "Cancel" button if you don't want to do this!
You can view and edit a previously-saved settings file's name and description by tapping the small blue arrow to the right of the file's name. You can overwrite the settings inside the file with a copy of the app's current settings, by tapping the "Update with Current Settings" button.
You might want to do this if, for example, you wanted to tweak the settings inside that file, without having to save them to an entirely new file. You can email a saved settings file to yourself, or to anyone else, by tapping the "Email This Settings File" button. When the email is received, the e-mail app on the recipient's phone will launch their copy of SkySafari, import the settings file into their list of saved settings, and let them restore the settings you sent them - all in a single step!
Then tap and drag the "grip" icon on the right side of the settings file to move it around the screen. Tap and drag the - minus icon on the left side of the settings file to delete it. Then tap the settings file you want to move or delete. To export a settings. You can also rename or delete observing lists here. To import a settings. If everything works correctly, your settings file will then appear in SkySafari's Save and Restore Settings section. If your settings file doesn't appear in SkySafari, make sure it's a valid SkySafari settings file, and that its name ends with ".
If all else fails, you can email your settings file to Simulation Curriculum technical support, and we can try to debug it for you. Android users can import and export settings files to SkySafari using their SD card. Then locate the Saved Settings folder within this folder. For example, if you own SkySafari Pro, your observing lists are stored in the following directory on your SD card:. You can also rename or delete settings files directly on your SD card.
If everything works correctly, your observing list will then appear in SkySafari's Save and Restore Settings section. There are a number of options availble for simulation the general atmosphere associated with rendering light and shadows and materials. Some documentation used to develop this tutorial are published on line in the V-Ray for Rhino manual published on-line at:.
There are a number of options availble for determining the the general atmosphere assocaited with rendering, light and shadows studies. Some documentation used to develop this tutorial are published on line in the vV-Ray for Rhino manual published on-line at:. Create a Rhino File with a ground surface, catenary curve generated vault such as was done in the catenary curves and vault tutorial and add a layer for a sunlight and create the 3d model below.
With the mouse cursor placed with the left-mouse button in the command prompt area, select the return key or right mouse button to place the sun light symbol at the origin of the x-y plane. An expanded dialog box that opens to the right.
That is adjust the upward poining triangles below the color histogram. Re-render the same view and note that the lighting is more diffuse and a background sky is now simulated. To begin, select the first tab at the top-left of the V-Ray Asset Editor to change the dialog box to the material creation tools. On the right hand side of the expanded dialog box , drag the diffuse light slider to the right to go from dark gray to neutral gray.
Once the cloth is selected, expand the parameters of the bump map on the right-hand side of the dialog box that follows. This will increase the density of the cloth pattern result in a smaller scale of is more appropriate.
In the parameters on the area of the texture mapping dialogue box, change XYZ size to 2. This basically told the Sky Digibox to download the channel list from another more available frequency. Note that changing the default transponder frequency setting on a Sky box in Spain, does not improve channel reception. Changing the default transponder frequency setting on a Sky box in Spain only tells the Sky box what frequency to download the Sky channel list for the Sky Guide from when being restarted after disconnecting from the power eg power cut.
In February , the frequency moved satellites and to a stronger, easier to receive beam. So you should no longer have to change the Sky Digiboxes default transponder frequency setting from , as this frequency is nice and stronger than ever. However, some people are unaware that they no longer have to change any of the default transponder frequency settings on a Sky digibox. This is because people have been using V However, this frequency is no longer a valid working frequency.
And so when the Sky Digibox is booted up, the box is trying and failing to receive its data from an incorrect frequency. And so it appears as if the Sky digibox is broken.
Remove the power cable from the Sky Digibox only. External factors such as internet congestion and home wiring can affect speed. Wi-Fi speeds vary by device and home entertainment.
