The focal length of my Orion Sirius Plössl 7.5 mm eyepiece that I added some time ago in SkySafari, appears in LiveSky as Orion Sirius Plössl 8 mm (I guess it is an approximation due to the conversion of the metric system to the imperial system).
However, the problem is more acute in StarryNight Pro 8, where the focal length of that eyepiece is transformed from 7.5 mm to 75 mm.I added yesterday, again, another Orion Sirius Plössl 7.5 mm eyepiece (to check if it was an error in my edition or had a synchronization problem). The error persists.
