Decent numeric info Not perfect, but if you're looking for numeric information on sun/moon/planet positions, rise set times, etc., this is the best available.

Equinox error There is a little error in Equinox time calculations. E.g. for 2016 your app shows Equinox time 4:21 for GMT=0, while official data is 4:30. I think your app doesn't take into account Mutations of the vernal equinox and aberrations.

Unlike the plethora of augmented-reality "sky map" apps available, this one seems to be intended for use with a telescope! Usable by amateur astronomers of any level of experience. If you can align your equatorial mount, you will find this app indispensable for viewing planets and minor bodies. It gives you the current celestial co-ordinates of the planet you wish to view, as well as for minor bodies such as the recently-discovered C/2020 F3. Far more useful than any other astronomy/telescope app I've tried.

Good But Selecting a saved location other than the 1st doesn't work. Please make it possible to select saved locations from a list. Thank you
