Scope Companion

Scope Companion


Scope Companion is software for computing performance parameters of optical equipment for astronomy, primarily designed for telescope novices and first-time buyers of optical systems.

Functions that are typically used in the dark come on red night view screens with adjustable screen brightness.

Upon input of basic specifications, such as aperture and focal length, Scope Companion calculates the ideal performance of the optics and plots a performance graph. Performance data can also be calculated for binoculars.

The imaging section calculates the field of view with a given CCD camera and lens/scope configuration. The data can be visually confirmed by means of a simulation against the surface of the moon and other objects.

Additional helper functions include a star transit counter for measuring the field of view of an unknown eyepiece, a dew point estimator, a compass, north/south polar finder, level meter, observatory clock, red light lamp, etc.

The dew point estimator supports built-in temperature/humidity sensors. The compass compensates for magnetic declination or points magnetic north.

An Observatory Clock in red night view mode with adjustable screen brightness is provided for use during observations. It shows local, universal, sidereal and martian time plus the positions of the Jovian moons!

Rise and set times are computed for the major solar system objects.

Visual aids include a red lamp and a magnifier implemented with the built-in rear camera.

BEFORE YOU PURCHASE:
1. Please be so kind as to send a report preferably with screen snap should you encounter any layout issues.
2. This application requires Android 2.1 or higher and a display which is to the Android standard.
3. This application operates in Portrait mode only. Small 240x320 pixel screens NOT supported!
4. Please contact the author, if you have any pre-sales questions.

Recent changes:
Ver 1.27: Adds a planisphere each to Day and Night tools. Performance plot corrected.
Ver 1.26: Removes Audio and Magnifier Camera as raising too many unused Permissions.
Ver 1.25: Adds twilight beg/end and moon rise/set to Observatory Clock
Ver 1.24: Adds sensor support to Weather, fonts for 'Solar System Now' enlarged and twilight beg/end times added.
Ver 1.23: Adds weather a station, adds moon phase icon to Observatory Clock
Ver 1.22: Adds comet tracking data (experimental), minor fixes

Useful appat the scope This is one of my most used apps at the eyepiece. Field Of View is great for working with eyepieces.

The developer is very quick to make changes and updates. I would imagine with all the flavors of Android versions not to mention the stuff that gets put on phones by the manufacturer and carrier it's very difficult to put out an app as well put together as this one. this app is well worth the money. We use it in my astronomy club a lot. clear skies

Great app and great developer. Definately worth emailing if you encounter a bug/issue or have a feature request.

Ok but... A good app but it appears only one scope can be defined at a time and eyepieces too.

Samsung s4 As soon as I try to open the compass or polar finder the app freezes.
