Astrolabium is an astronomical expression. It is a discodial instrument to measure
angles at the sky, invented 2000 years ago.
My Astrolabium is a program to measure distances as angles on astrophotos. It can
be used to measure the distance of double stars, the diameter of planets, comets
and Messier objects. You can also measure the absolute diameter of moon craters.
Vice versa, if you know the angle, you can determine the pixel size or focal
length of your camera.
How it works
Enter focus length of your telescope or lens and select your camera from the list.
Then mark two points
on the image: one with a left mouse click, the other with a right mouse click. Then
the distance will be displayed in the status bar as distance in degree, arc minutes
and arcseconds. If you enter the distance to the object, the absolute distance will
be shown, too.
The selected area is magnified in the upper left corner while you press the mouse
button. You can move the selected point when you keep the button pressed and move
the mouse.
With version 2.0 the camera data can be determined automatically from the Exif
information of the image.
Astrolabium is freeware. You can use it for free without time limit but you use
it on your own risk.
