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.

1. If Comet is selected, the illumination of unselected Comet is diminished in order to easily distinguish the selected one from others.
2. A swipe icon that allows you to scroll the star chart is set up on the lower right corner of the screen. If the double circles swipe icon appears on the screen, it allows you to swipe the star chart left and right in semicircular star chart screen.
The star chart can be moved up and down or left and right with a swipe in the full screen star chart.
Besides, the star chart can be zoomed in with a pinch gestures up to 5 times in the full screen star chart.
Tapping the swipe icon will change the screen from the star chart that synchronizes with a real view of night skies to the fixed star chart that does not follow your viewing direction, and vice versa. The present mode of the swipe icon will be switched each time the swipe icon is tapped.
If your on-line terminal unit does not have a function of electronic compass, the star chart is stayed with the swipe mode and cannot be switched to the other mode displaying your viewing direction.
3. The stars of 4.5th magnitude and brighter are displayed in the semicircular star chart and the stars of 6th magnitude and brighter are displayed in the full screen star chart.

Halfdonkeyed,
Missing magnitudes
Also missing easy way to set time to right now. Date time and vector text could be larger.
Great for free :)

AstroGirlBunny,
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!!!!
sorensenbrad,
Visually Stunning
While the app looks awesome I have a few asks…
I only see the one comet that comes with the install, why can I not see and explore lots of comets?
There should be a DB of comets to
Explore.
Also the time and date should be able to be adjusted to view comets in DB.
This being said the app is visually stunning and has tons of potential. I really look forward to future updates.

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!
