Hello Bernd and all,

I have created two Guide9 screenshots as small gif files to show the
problem of the MP display.

This first image looks normal and shows MP to the set +17.0mag limit.
See the image center cross near Vega.

Now in this second image I only have set the image center with one mouse
click a little bit to the north (see the image center cross is still
near Vega) and now most of the MP are off. And if I go back to the
previous center position all MP are shown again. This is the strange
behaviour of Guide9 I can not explain at the moment.

Help would be appreciated.
