[OpenLayers-Users] Layer.Google scaling

[karpi]

Hello..
Im working on this map:
http://gismaster.liberix.cz/google/openlayers_czrep

Please, what i do wrong, then i can not zoom deeper into g-layer..
when i zoom max in openlayers, my "observation point" is still too high
against original gmap interface..

for comparsion: max zoom on openlayers:
http://gismaster.liberix.cz/google/openlayers_czrep.html?lat=50.08693&lon=14.41569&zoom=15&layers=B00T
..and even not full zoom on gmap:
http://maps.google.com/?ie=UTF8&om=1&z=17&ll=50.08615,14.41462&spn=0.004674,0.008487&t=h

How do i can zoom deeper, plz?
I was playing with maxZoomLevel, but without any advance 

                                                         thanks
