Comments about Telescope calculator Android Version

App seems pretty useful and has lots of good data. I only had two issues. First, the help responses to the question marks is in Russian (?) and so no help at all explaining what the values are. Second, quite often switching values or screens results in the view through the eyepiece shrinking in size. The whole eyepiece shrinks, not just what is shown as being the view. Example, moon is almost filling the eyepiece, switch to another view or change a value, switch back to main screen and the eyepiece circle is now 1/4 size and the moon still almost fills it.
Aside from the full screen ads that pop up in the most inappropriate way, it is not accurate at all! Comparing the sizes it provides with what I see in my telescope, it is far by quite a bit.
Very useful in planning viewing sessions, eyepieces and photography by providing excellent data on what to expect. As a beginner, I refer to it a lot but it must be equally useful for experienced astronomers, too.
