Description: M11 looks very disappointing with the 40mm Ploessl, it's only 
a smudge of faint light around a star. Even the 18mm Ultima didn't bring 
out any details, with averted vision one had the impression that some 
stars could be seen in the cluster. Things totally changed when using the 
6mm LV from Vixen: due to the dark background stars stood out like diamond 
dust - the view was extremly impressive and satisfying. A rewarding object 
for city skies! Within the same field of view (18mm) you can see a nice 
double, ADS 11719.
