Description

The Comet Book app clearly shows when Comets can be viewed and in which direction. The direction and elevation of a 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 though they have 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 a Comet by using Comet Book as a guide to the direction and elevation of the comet.

In addition, the new “3D Solar System seen from Space” mode allows you to view the motion of Comets and planets turning around the sun. Please take a look the comet’s movement around our solar system.

It is beautiful!

It is too bad the other user did not try it out after the update. Then update his review. The tutorial was a thing of beauty. Afterwards, I checked out different comets, walking through them like the previous instructions taught me. Everything works wonderfully! The developers did an amazing job!!!!

PERFECT comet app!

I downloaded this after I heard about Neowise being visible this evening and I am not disappointed at all! This app is perfect and I will continue to use it for years to come!
