Want to know how light pollution will affect deep sky objects in your area?
It's very useful if you plan on buying a telescope and you want to know how deep sky objects will look through it from your area.
What you can do with this app:
Choose from over 100 of the brightest clusters, nebulae and galaxies and compare their angular size with the full moon
for a precise estimate of how large that object will appear in your telescope!
For an accurate calculation of how bright a particular galaxy, nebula or cluster will be in your eyepiece, first
enter the aperture of your telescope, turn 'Light Pollution' on, and choose which of the 5 light pollution levels best describes where you live.
All statistics and numbers have been fine tuned to give an accurate measurement of how the object will look through
All deep sky objects have been resized to precisely the size they would appear if next to the full moon.
You don't even need a telescope to make good use of this app as over 30 of these deep sky objects can be seen with
the naked eye(Including 5 galaxies!)
Extremely useful for astrophotogrophers, amateur astronomers and star gazers alike!
Know of a bright deep sky object that isn't in this app? Let me know and it may be included in the next update.
Dark interface for night use
-All 110 Messier objects
-The brightest NGC objects
-Simplistic user interface
-Accurate light pollution predictions
-'Show Moon' button that places the moon beside each object for angular size comparison
Tip: To get the most out of the light pollution aspect of this app, use in a dark place where your eyes can adjust to see the faint objects on the screen!

Consider other Editions for more stars / objects.
Planning tool. Filter NGCIC object database by observer location, sky condition, astronomical equipment, time range of observation and object features (type, dimension, magnitude, minimal altitude, visibility). Create up to 4 observation lists. Easily track observed and remaining to be observed objects with note taking tool. View them on the Sky Chart
Offline images. Integrated set of deep sky object images
DSS imagery support. Download DSS (Digitized Sky Survey) images of any sky portion into offline cache and overlay it on the star chart
PushTo for dobsonian mounts with setting circles. Level your dobsonian mount and perform one star alignment. The program will automatically recalculate az/alt numbers to easily hunt the object
Nebula contours. Contours of famous nebulae
Object contours. Ellipse in real dimension and orientation on the sky chart
Bright Solar System objects. Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn shown on the sky chart
Night mode. Red keyboard and menus
Note taking. Take text and/or audio notes
Observing places. GPS, manual coordinates, custom lists
Equipment. Keep track of all your telescopes and eyepieces. Use them for object visibility calculation and star charting
Twilight calculator. Sun, Moon rise / transit / set. Moon Phase. Civil, Nautical, Astronomical twilights.
2 visual themes (bright and dark)
Powerful share/export/import capabilities (of databases, observation lists, notes)
GPS and network location:
Needed to calculate true north.
Needed for downloading ads and for completely anonymous usage statistics. Usage statistics can be disabled in the settings of Compass.
While using the light, you cannot use the camera application.
A widget is also available. Lighting with the widget, automatic turn-off by the timer is not available.
How to add the widget:
Android Home Screen, Menu Key→Add→You can add the widget.
How to change the design and size of the widget:
Main Menu→Menu Key→Settings
We don’t know if it will be a problem with the hardware to light on all the time so please use it at your own risk.
To cope with some failure of certain home applications, when the widget is used, the service is temporarily used. Therefore, when you click the widget to light on, there is a little time lag.
We cannot meet your request to add icons of certain models. Thank you for your understanding.
Shows red screen on phone to light the night without ruining your night time vision.
Good for activities such as camping, astronomy, ???
wrote this small app because i needed it, now sharing it.
- Adjustable brightness
- small download size
- no ads
The application is able to be displayed in normal mode as well as night mode.
This Application 'Sidereal Time' displays sidereal times (ST) as well as several other time standards.
You will not only find the actual date and your local civil time but also 'Universal Time Coordinated' (UTC), your time zone and the difference between UTC and your time zone. The Julian Day count (JD) and the modified Julian Day (MJD) of course are displayed as well.
This application "Sidereal Time" shows the relevant scientific and common time formats.
It may be of interest for all areas of chronology and geography, geodesy, geophysics, meteorology, satellites (ISS)
and astronomy. It keeps scientifically interested people, hobby or amateur astronomer always up to date.
