I made the app with a friend. We are not a company looking to make millions - we are amateur astronomers and we make apps in our spare time. We think we have a great observing tool we’d like to share.
The App provides a catalogue of hundreds of northern and southern hemisphere Double Stars that can be filtered by your location, date, time and your equipment - for both binoculars and telescopes. It even has naked eye doubles suitable for rural or urban observers. Rather than find Double Stars from a book or chart let the App create a unique list just for you based on what you can see.
Once you have filtered the catalogue to your location and equipment, Double Stars can be added to a Sky Tour. The conventional Double Star data is fully loaded (Magnitudes, Separation, Positive Angle etc).
The App also generates Smart Tours (think iTunes Smart playlists) for wide pairs, tight doubles, colour doubles etc - all based on what you can theoretically see tonight. The App helps you locate each Double Star with RA & Dec as well as interactive Alt Azimuth coordinates.
Furthermore, based on the information entered about your scope it will even suggest an eyepiece to give you the best chance of splitting each Double Star.
The Sky Tour is viewed using a variable red ‘night vision’ mode that we previous trialled successfully on one of our other apps (‘Night Notes’). A Location Assistant helps locate the star using its live position if you don’t have a computerised mount. Try strapping your iPhone to your scope (with an iPhone running armband) to create a low cost GoTo finder!
We carried out extensive testing over Winter some willing volunteers. Their input has been invaluable and the app is now greatly improved thanks to their help. We think this will be a great App for amateur Double Star fans to plan and execute successful observations.
Finally, if you like it, please leave a review on the AppStore and then tell your friends! Happy splitting!
