Description: The sky wasn't really dark at the time I observed M11 with 
the Celestar 8 and a 40mm Ploessl, but a great number of stars was already 
visible. After having seen this cluster under much darker skies in the 
city with my 4.25" newtonian, I have to say that those 4 more inches DO 
make a difference.  M11 was just a haze in the 4.25", with the 8" SCT it 
was like tiny pinholes in a grey velvet. The famous V shape was buried in 
the shere number of stars that surrounded a brighter star just in the 
middle of the cluster.
