Comet Book

By Vixen Co.,Ltd.

Open iTunes to buy and download apps.


The Comet Book App clearly shows you when and from which direction Comet can be viewed.

The direction and elevation of Comet can change noticeably in a day due to its fast apparent motion. The moon and a bright planet may be convenient as a guide to find the comet; nevertheless they have a large apparent motion, too.
This App determines where Comet is in the sky when it becomes visible at your observing site.
You can easily start your observation of Comet using Comet Book as a guide to the direction and elevation of the comet.

The following new functions are added to Ver.1.1 Comet Book.

1. Night Vision Mode
Accessing the “Setup” menu and turning on the night vision mode will change the star chart to an amber color. This prevents your night vision from being affected by the bright screen.

2. Support Page
Help, support page and privacy policy are provided in the Setup menu. The Support Page links you to the Vixen web site.

3. The present latitude and longitude recognized by the Comet Book.
When you view stars in the night sky, the date, time and the present latitude and longitude are essential information to know the direction and altitude of stars and comets. The same information is necessary when you display the star charts using the Comet Book. Pressing the “GPS Receiving Status” icon will show the location of your observing site on a simplified world map.

4. Updating orbital elements for Comet.
The Comet Book updates orbital elements for Comet on startup.
