Some high school ...

Redshift has beautiful made from version 3 to 4 a good for professional astronomy software.
But this I miss in five! Although there are added some new features, though most in the graphic area: So the solar corona, comets or even the moon shadow of a total solar eclipse is carried out realistically. Also, the star number of 18 million. to 20 million. increases. And newly discovered asteroids, comets and moons were added. However, it is not really to assume that at least one Normal User 20 million. Star needs.
Very good I find OpenGL support, because the work area to move the manellen no longer is processor-heavy and it runs even smoother.
The operation is largely identical to the version 4 of Redshift.
So the brightness classes have been extended for the better. Such as visibility Klaasen, brightness classes, or color classes in mists.
So lets take a look at the visibility of an object to the best date and time. In a table, the data are very detailed and printable. The display rise / set is still maintained even when extended. I like that!
A night mode with integrated, in which the brightness of the program is turned down to a minimum. Also allows you to adjust the amount of red.
Furthermore, the astronomy lexicon, the Photo Gallery and the Astro-records are maintained.
My opinion is: Who owns the 4-version, and can do without these new features and updates may reassured 4p stay in because the differences turn out not so great!
Beginners I recommend the 5 course!
Many Greetings
