Summary	0001611: Searching objects returns slightly wrong coords
Description	With OpenNGC catalog selected, if you search for an object with an high FOV applied and zoom in after the search you can notice that the field is not perfectly centered on the object, and neither the label is. If you do the same search with a small FOV selected (< 8°) the result is the object perfectly centered. Maybe it's a rounding error? Using SAC this behaviour is worst: even with a small FOV, the search result is always wrong, it's like as the program uses different coords for the search and to display objects.

This was a bad idea and I remove that. I also make a correction to search SAC or OpenNGC first depending on the setting. https://sourceforge.net/p/skychart/code/3446/
