AstroCalc is also available in French and in 4 other languages !
(Spanish, Russian, Ukrainian, German)
AstroCalc enables you to :
- To calculate the position of planets and give their appearance.
- To calculate hours of Rising/Transit/Setting
- Visualization of the apparent diameter of planets ones compared to the others…
- Visualization of the position of planets on the ecliptic.
- Visualization of planets in heliocenric position.
- Positions of the satellites around Jupiter, as seen from Earth.
- Calculate the position of comets...
- Download the appearance of the sun directly on web ( SoHo ).
- And many other possibilities.....
The calculations are based on algorithms from Jean MEEUS
("Calculs Astronomiques à l'usage des amateurs") as well as personal adaptations for special events.
The accuracy is of course limited, however this accuracy is sufficient for every amateur astronomer.
Compatible with Win 98/ME/NT/2000/XP
CroTool makes it possible to record, to manage Report of Astronomical observation (CROA)…
-Crotool is equipped with many fields (59) which you can fill to compile all your information of observations
-Additional fields make it possible for the astrophotographer to record their parameters, whether it is with a webcam, CCD, or a Numerical Camera.
-CoTool can export a CROA into a .txt file to be able to print it, or to directly copy into the clipboard to be able to send it by email...….
