FOViewer is a handy astronomy tool for every stargazer. It allows you to calculate things like the magnification of your particular telescope and eyepiece combination. FOViewer 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. You can add your own equipment to FOViewer to get spot-on predictions for your telescope / eyepiece combinations. If a particular telescope / eyepiece combination results in a magnification that goes beyond the maximum useful magnification of your telescope, then FOViewer will notify you by giving the magnification a red background and showing an alert.
Apart from the magnification, the field of view and the F ratio of your telescope, FOViewer will show you the local time, your GPS coordinates and a compass to help you get that GOTO telescope properly aligned!
So to summarize, FOViewer;
• Calculates the magnification, F ratio and field of view 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 photos of well-known celestial objects. Objects for both hemisphere’s are available.
• Let’s you add and remove your own telescopes, eyepieces 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 small compass.
A few pointers on using FOViewer.
• Tap the plus icons to add your own equipment.
• Tap the minus icons to remove equipment from the lists.
• Tap the preview images to cycle through objects.
• Frequently calibrate your build-in electronic compass by drawing figure 8’s in the air.
