SkyGuide Description |
|
| |
You need a Newton MP2X00 to run this. If I get enough requests Ill consider writing a version for earlier Newtons.
At the moment SkyGuide picks up the time and location on Earth from your current location according to the Newton.
The brighter line represents the horizon and yes, you can see through the Earth.
The dimmer lines represent Right Ascension (RA) and Declination (Dec) fdef09
Stars down to magnitude 4 are displayed.
The Planets, Sun and Moon are represented by small circles identfied by a three letter abbreviation. The are not to scale.
On the lower left the following information is displayed.
Viewing location on the Earth in longitude and latitude
Local Mean Time (Time according to your longitude)
Greenwich Mean Time
Local Siderial Time
The + and - buttons zoom in and out. The number between the buttons represents the zoom factor on an arbitary scale. The most useful zoom factor for locating objects is probably 500.
The N button is used to refresh the display according to the current time.
The arrows allow you to pan across the sky, however it is probably faster to simply click on the point of the sky where you want the display to be centred.
The numbers below represent the direction you should be facing to see what the Newton is showing you in the real sky. Sometimes there are 2 sets of numbers, one of these will usually be correct. Im still working on this.
The first number is the azmuith, or in other words the direction you should be facing taking North as 0 degrees.
The second number is the elevation, or the angle from the horizon you should tilt your gaze.
The i button in the menu has an about box. If you feel the urge then send money to the address supplied.
The Direction menu sets the viewing direction.
North, South, East and West are pretty self evident.
Zenith will look directly overhead.
Horizon will look at the horizon.
Nadir will look at you feet.
Custom doesnt work properly at the moment.
The View menu controls what items are rendered in the display. This can be used to speed up the program.
RA Dec will display or hide lines of RA and Dec
Horizon will display or hide the horizon line
Planets will display or hide the Planets, Sun and Moon
Stars will display or hide the stars |
