Hi everyone!
It's been a while, my last post was in 2012 8-|
But I return with good news, the FOViewer app has been completely redone!
You can find
FOViewer in the Play store.
FOViewer NG is a handy astronomy tool for every stargazer or astrophotographer. It allows you to calculate things like the magnification of your particular telescope and eyepiece combination. FOViewer NG will also show your field of view superimposed on astrophotos of well-known objects. That way you can get a good prediction of which eyepieces to use to optimally view your celestial targets.
Features? Features!
Calculates the magnification, F ratio and field of view for a particular telescope / eyepiece combination.
Calculates the exit pupil for a particular telescope / eyepiece combination.
Alerts you when your magnifications goes beyond the maximum useful magnification of your telescope.
Shows you your field of view as a circle drawn on high-res (up to 2000x2000px) full color photos of celestial objects. All objects of the Messier and NGC catalogue are available.
Shows the field of view of your CCD camera or DSLR camera as a rectangle drawn on photos of celestial objects. The field of view rectangle can be rotated. All objects of the Messier and NGC catalogue are available.
Lets you add and remove your own telescopes, eyepieces, CCD camera's and barlow lenses.
Shows your local time to help you configure your GOTO telescope.
Shows your current GPS position.
Shows you where magnetic north is by means of a compass.
Shows you the current moonphase.
Shows you a clear sky clock for your current location.
Much more!

The apparent size of the solar system objects is calculated in real-time using up-to-date solar system data from a web based service.
